Boomer begins having suicidal thoughts when she begins to suspect that she's a Cylon, and Baltar - who knows for a fact that she is - pushes her over the edge, causing her to shoot herself. She ends up jerking the gun away and letting the bullet pass through her cheek, leading her to wonder later whether her programming prevented her from killing herself until after her mission was accomplished, or if she was just a lousy shot.
In later seasons, this also happens. Dualla does this after returning from the nuked Earth.
D'Anna Biers is Driven to Suicide for a different reason: After her first death, she becomes obsessed with the "place between life and death" and begins to kill herself...over and over in hopes of glimpsing into something she isn't supposed to know. She gets an actual an actual one after the Fleet comes across the nuked remains of Earth. She chooses to stay behind and presumably dies. Since she was the only living Number Three at the time, this action also ends her line.
A favorite tactic of the First Evil on Buffy the Vampire Slayer is to use its shapeshifting powers to play mind games to trick heroes into destroying themselves. It actually talked potential Slayer Chloe into hanging herself in "Get It Done".
Spike also tried to kill himself after he got chipped, though it seems to be played for laughs from the way he delivers his line in the scene.
a Dalek chose to blow itself up rather than become tainted with human DNA. The only time the word "EXTERMINATE" could ever be turned into a sad moment.
In the Titanic episode, one woman makes a not-entirely-necessary Heroic Sacrifice shortly after her husband dies in front of her, and even more shortly after the Doctor promised to save her and she responded "What for? What am I going to do without him?" It's not quite the same as jumping in front of a truck, but, well, there are ways of dealing with Mecha-Mooks that don't involve throwing a rope around one and jumping into a reactor with it.
Amy in "Amy's Choice" after Rory dies in the dream world. Although Amy, the Doctor, and Rory are given a choice between two worlds and must figure out which is real, Amy chose Leadworth as the false world while having no way of knowing because either way she’d be with Rory, saying if this was reality, she didn't want it (the only way to leave the false world is to die. Die in the false world, wake up in reality; ask what happens if you die in reality.note You die, stupid. That's why it's called "reality.") She basically smashes her car into a wall at maximum speed to be with Rory.
It's heavily implied in "Turn Left" that the Doctor simply let himself drown with the Racnoss when Donna wasn't there.
In The Sun Makers, Leela spots the first person they see on Pluto — going to throw himself over the building side.
And then there's Adelaide Brooke in "The Waters of Mars" who committed suicide because her death was a fixed point in time necessary to ensure the spacefaring future of the human race.
Rory in "The Angels Take Manhattan." He'd rather kill himself rather then have to age to death in the Angel's farm without Amy. Plus it helps that it creates an Angel destroying paradox.
Ted, the hospital's lawyer, who is eternally depressed and contemplating suicide. Typically he stays on the roof of the building, looking down, waiting to gain enough courage to take the final step, often while Dr. Kelso watches in sadistic amusement. Something always happens that prevents him from jumping, to Kelso's chagrin... except one time when he's about to turn back, but accidentally falls down (Dr. Kelso came up onto the roof blasting an air horn, the surprise causing him to fall). He survives as he lands on a large pile of garbage bags the Almighty Janitor had put there (the whereabouts of which had been part of another plot). Who then gives Ted advice on a location to 'jump' from that will be successful.
Elliot confesses that she once tried to drown herself, although this wasn't played for laughs. It was actually mostly ignored after that episode, as all the characters became generic sitcom characters.
Played for laughs once. Elliot admitted that she didn't try to stick her head in an oven. When her head gets really hot, she pisses herself and she didn't want to be found in a puddle of her own urine.
Dr. Cox unknowingly transplants rabies-infected organs into 3 patients, killing them and driving him to nearly drink himself to death.
While Supernatural's Dean selling his soul so his brother can live again in "All Hell Breaks Loose" might look like a Heroic Sacrifice at first glance, it's really, really not. He still thinks he should have died at the beginning of the season, he has a massive guilty conscience about failing to protect his brother, you only have to watch the rest of the season to know that he hasn't been in the best of places for a good, long time and Azazel even says he has a pathetic, self-loathing desire to sacrifice himself for his family. In "Dream a Little Dream of Me", he finally seems to get over his suicidal nature and realises he doesn't want to go to hell. Too bad he's doomed anyway. That's not the only time he's been driven to try (it just succeeded that time). There's "Faith" where he accepts his impending death and lets the reaper try and take him. There's "Dream A Little Dream Of Me" where he takes his rage out on what looks like himself and shoots the doppelganger dead. There's "Croatoan" where Sam might turn violent due to infection and instead of running away, he locks himself in there with him, and then there's "What Is And What Should Never Be" where his perfect girlfriend definitely looks like the Reaper in "My Time Of Dying", his greatest wish is to get some rest (it's unclear whether he just wants a bit of peace or, um, forever rest) and he needs to kill himself to get out of his dreamworld but is perfectly fine with the other option which is dying for real. Oh, Dean!
In the season 5 finale, Dean would rather die with his brother than not be there for him when Lucifer has taken over Sam's body and all hope of stopping him seems gone. He was lost enough throughout the season that he nearly said "yes" to let Michael possess him so Michael could kill Lucifer even though that would raze the world.
Sam was suicidal throughout season five as well, first preferring death to possession, then playing out a Self-Sacrifice Scheme to lock Lucifer back up by saying "yes" to let Lucifer possess him and walking into the Cage. If Sam succeeded, he'd be trapped with a vengeful Lucifer to be tortured for eternity by him. The whole demon blood thing the season before only came about because Dean died and Sam thought he had to use enough blood-fueled power to kill himself killing Lilith to prevent the Apocalypse. This is well after he tried to get Dean to kill him so he wouldn't become a monster.
For various reasons, Dean's behavior in most of Season 7 was borderline suicidal.
Castiel, filled with regret over his decisions regarding Crowley and the souls in Purgatory, actually does succeed in sort of committing suicide in Season 7 by walking into a lake. His "death" doesn't stick, but in Season 8 he admits to Dean that he can't go back to Heaven, because if he sees what his actions have done to it, he may "kill himself".
Another episode featured a monster that drove people to suicide by mimicking their dead loved ones and telling them to kill themselves so they can be together again.
The episode "Wishing Well" played this for laughs with a teddy brought to life by a little girl's wish that attempts to blow his own head off with a shotgun. He fails.
In The Vampire Diaries it happens a bit too often with the Salvatore brothers, but always averted. First both of them wanted to die instead of drinking human blood and becoming vampires. Stefan changed his mind and conned Damon into following suit. Then when Stefan "fell off the wagon" and started drinking human blood again... well, that didn't work either.
And in the first season finale Jeremy. Sort of.
According to the Season 4 premiere, Elena's actions in the S3 finale were a result of this.
In Upstairs, Downstairs there's James Bellamy, Emily the Maid, and, in the reboot, Lady Persephone.
In the Charmed episode "Murphy's Luck", a darklighter tries to drive a future whitelighter to suicide, since the only way to keep a person from becoming a whitelighter is to have them take their own life. Then he turns his powers on one of the main characters...
Later on, Cole wanted to kill himself and had tried many times but can't because he's too powerful.
Leading to a great line, Cole (conjuring a guillotine): I can't wait to see how I survive this.
On The Colbert Report, Stephen illustrated the 'mixed messages' within a Presidential speech by playing a series of clips, then cutting back to the desk in between. Good news - "Yaaay!" Bad news - "Boooo." Good news - sucks on cigar. Bad news - sucks on gun barrel. (Luckily, the next clip was good enough to dissuade him from going through with it.) This upset a few fans...
LOST is a fairly suicide-heavy show. In addition to Sawyer's father's murder-suicide (in flashbacks), we've seen Locke, Jack, and Michael on the verge of suicide. In Jack and Locke's cases, they were interrupted before actually making the attempt. Michael tried at least three times unsuccessfully. Richard has also tried, but his immortality also extends to a inability to kill himself.
Happens to more or less half the cast of Rome, in some cases because a character is based on a historical figure who took their own life. Some of the more notable ones include: The death of Niobe, who throws herself off a balcony so that Vorenus won't have to take her life in season one, the fate of both Antony and Cleopatra in the series finale, Brutus walking in among the enemy soldiers in a suicide-by-making-them-kill-me fashion in mid-season two, followed by Servilia and her slave in the next episode.
While Dr. House is a self-destructive bastard with a death wish, the only time he's ever properly tried this is in "Merry Little Christmas", when the Tritter deal got too much for him to handle and he ended up overdosing on a dead patient's meds. He also once electrocuted himself specifically in order to undergo a near-death experience.
In "Simple Explanation" ,Dr. Kutner kills himself. And nobody has any idea why. In Real Life, however, everybodyknows why. Kal Penn got a job with the Obama Administration, and you can't be a TV regular and work for the White House at the same time.
It's been strongly hinted throughout the series that Taub tried to kill himself in medical school because of the pressure.
The patients of the week in "Unwritten" and "Painless" attempted to take their own lives in their respective episodes' opening scenes.
Klingons were known to engage in ritual suicide if disability forced them to be a burden on their families. When Worf was badly injured in an accident, he asked Commander Riker to serve the role. Riker heatedly refuses, castigates Worf for choosing not to fight to survive like so many of their comrades did, and points out that Worf's son Alexander is old enough to perform the ritual instead. Specifically, Klingons can't kill themselves as it's dishonorable, so asking a family member to do it is a way round this. In a Deep Space Nine episode Worf's brother Kurn asked him to perform this duty after his family had been stripped of their titles and honor by Chancellor Gowron. When Worf doesn't go through it, and various efforts by Kurn to die in the line of duty fail, Worf comes across his brother drunk with a disrupter in his hand, trying to work up the courage to shoot himself in the head, which would mean eternity in Klingon hell, "but at least I would be with other Klingons."
One planet had every member of its society committing suicide when they reached the age of sixty.
Suicide as a result of Psychological Interferrence was the subject of "Eye Of The Beholder", where empathic impressions from a past suicide caused several empathic individuals in the Enterprise crew to experience hallucinations forcing them to attempt the same thing (some of them succeeded, others didn't).
One episode ("Tin Man") had a lonely spacefaring creature trying to kill itself by sticking around a star about to go nova. Only to be subverted by finding companionship from a telepath, so that Tin Man would no longer be alone and the telepath only heard Tin Man's singular voice.
In one episode, even Data mentioned that during his early formative phases, he found the process of becoming sentient so difficult that he considered deactivating himself, an act other crew members equated to suicide.
In the Deep Space Nine episode "Hard Time", O'Brien gets implanted memories of spending a 20 year prison sentence as part of punishment for a crime. In these fake memories he killed his cell mate over some food (that the cell mate was going to share with O'Brien anyway). O'Brien has such a hard time dealing with his actions, even though they weren't real, that he nearly commits suicide and Bashir has to talk him out of it.
Dr. Julian Bashir: The Argrathi did everything they could to strip you of your humanity. And in the end, for one brief moment, they succeeded. But you can't let that brief moment define your entire life. If you do, if you pull that trigger, then the Argrathi will have won - they will have destroyed a good man. You cannot let that happen, my friend.
Serena van der Woodsen returns home from a year at boarding school because of her brother's attempt at suicide.
Chuck Bass had to be talked down from the edge by Blair, following the sudden death of his father.
Barney Stinson of How I Met Your Mother provides a rare version of this trope played for laughs, attempting to jump off Robin's balcony when he hears that Brover (his new dog/wingman) has to be returned to its true owner.
The Stargate SG-1 episode "The Light" deals with a Goa'uld discovery that's described as being similar to an opium den. Upon discovering it, the people who witnessed the titular light go into "withdrawal" when they return home, and attempt suicide. (A one-off character kills himself with the kawoosh and Daniel unsuccessfully tries to jump off his balcony.) The situation was resolved, though.
An episode of Stargate Atlantis had a society where people were required to commit suicide at the age of twenty-four; this turned out to be a form of population control designed by the Ancients to keep the population contained within the field of the protective shield that hid them from the Wraith.
A later episode actually had Sheppard drive another man to suicide, specifically "suicide by being fed on by starving Wraith", since he was responsible for McKay's sister being infected with deadly nanites. The Wraith was the only one competent enough to deactivate them in time, but was too malnourished to do the job.
In Stargate Universe, Spencer is driven to suicide through the combination of withdrawal from sleeping pills and the stress of being stranded on Destiny.
On Fringe, a man that Walter describes as a "reverse-empath" can project his self-loathing and suicidal thoughts onto other people, making them commit suicide. It may be a Take That to The Happening.
Many people throughout the Law & Order franchise (especially Law & Order: Special Victims Unit), but notably in the Law & Order episode that introduces Det. Lupo: His brother is one of a number of people who were helped to commit suicide, and he's looking for their "helper". That person's father, a Dr. Kavorkian expy, takes responsibility before dying of his own poison.
In The Tudors, the series version of Cardinal Wolsey perfectly illustrates that trope. Historically, he's said to have died of illness and exhaustion while being detained (and that is already quite ugly), but since he was a) stripped of all titles, offices and incomes, b) kicked out of the royal council, c) sent to jail, d) separated from his beloved Joan and their two children (Yeah, children. So what ? Priests must not marry. That's all), and e) waiting to be trialed for treason, the issue of said trial quite painfully obvious, the suicide option seems sadly logical. Maybe this is a case of Truth in Television, we'll never know.
On Dead Like Me, the main characters take and guide the souls of people dying from "external influences", including suicides. One notable subversion, however, comes when Daisy's target seems to be on the verge of suicide: Unfunny, unattractive and leaving a speed-dating session withnonames, he is standing on a roofs' ledge and looking down. As Daisy approaches him for the Reap, the camera pans down to reveal that he is already dead, with his body lying on the distant pavement. His soul comments that he slipped.
On Mystery Science Theater 3000 episode 819, Invasion of the Neptune Men, a giant nude statue of Bobo is more than Pearl and Observer can take, so much so that they tussle over who gets the noose—until they realize that they have to fix the time-stream to save Chicken in a Biskit.
In Caprica this was the apparent fate of Amanda Greystone at the first mid-season Cliff Hanger. That same episode, Zoey Greystone/U-87 also embraced this trope, given that it involved a fiery car crash. Also that same episode, Tamara Adama shot herself, though she knew she wouldn't die from it.
On Wiseguy, crime boss Sonny Steelgrave chooses this over the imminent humiliation of arrest, prosecution, and lethal injection. His nervy exit-scene actually rates as an Expiring Moment of Awesome.
In The 4400 Isabelle tries to kill herself by jumping off the 4400 Center (a very, very tall building) because her rapid aging is killing her mother. Unfortunately, she discovers that she's practically immortal, so this doesn't work. Lily then talks her out of trying again.
In a subversion, a few episodes later, a man discovers Isabelle floating face-down in a lake. After he saves her, she tells Shawn that she wasn't trying to kill herself. She just wanted to learn to swim!
In Degrassi High Claude Tanner commits suicide because Caitlin doesn't love him. This lead to either episodes 25 and 26 (Showtime part 1 and 2) or just episode 26 being cut.
In Degrassi episode "Bitter Sweet Symphony", Campbell Saunders commits suicide following Zig calling him a psycho and telling him to get out of Maya's life forever. In fact, Cam's character was planned to commit suicide since he was conceived by the writers. Nearly all episodes and stories revolving around Cam were ultimately to lead to and foreshadow his death.
The Red Dwarf episode "Back to Reality" featured the Despair Squid, a genetically-engineered predator which used hallucinogenic ink to induce suicidal depression in its victims, including fish. Even the entirely electronic Rimmer and Kryten were affected.
In the Terriers episode "Change Partners" a masochistic banker who forces his wife to indulge his cuckolding fantasies by having affairs is Driven to Suicide when he realizes that his actions are hurting her. His suicide note reads "I only meant to hurt myself."
On ER, Gant's death is seen as this, though it's never established for certain whether he accidentally fell or deliberately jumped onto the tracks, but Carter seems to feel that the latter is the case, as Gant was depressed and being subjected to relentless criticism from his superior.
Horatio himself feels suicidal after he joined the Navy and is pursued by a particularly nasty bully. As a Death Seeker, he decides to challenge him to a Duel to the Death. Either outcomes are good — he either kills the bully or be killed. Both will free him.
After a couple of years in a Spanish prison, five failed escape attempts, and a month in an oubliette, Archie Kennedy is pushed over the brink by Horatio's arrival (likely because it brought back memories of his old tormentor Simpson, who he didn't know was dead — after all, immediately after Horatio's arrival Archie started having seizures again, which had only happened around Simpson before). He tries to starve himself to death and Horatio notices just in time to save him.
In the CSI: Crime Scene Investigation episode Unleashed, a pregnant teenage high school student named Maria Diorio (played by Brooke Anne Smith) committed suicide by hanging herself with her lover's belt after various traumatic factors, such as her father's death, her pregnancy, her lover's refusal to help her at her time of need, and especially the fact that an Alpha Bitch and her friends, out of resentment that her lover, the homecoming king, dumped her for Maria, decided to get back at her by making obscene posts enmasse, create a website where they planted Maria's face onto a Donkey with a caption stating "I'm a stupid bitch!", as well as a viral video that allegedly had her saying in cheerleading cheers that she was a whore, getting over 1,000,000 hits.
Played for Laughs during the Pirate episode of Married... with Children, where several ship crew members do this for having to endure the (supposedly long) singing from the dreadful pirate, Ruvio the Cruel. Apparently ship wayfarers consider musical-version performances to be torture...
Even Sesame Street had this in an animated short called "King Minus". If he touches anything at all, it is immediately annihilated. This includes the Damsel in Distress he meant to save. He can't live with himself after that.
On Kamen Rider Blade, Hajime is forced to become his Joker self and begin The End of the World as We Know It. After trying several times to resist it, he ultimately finds that it's impossible, so he tries to kill himself with his own weapon to stop it. It fails, because as an Undead, he's immortal. Later, he attempts to force Kenzaki to seal him, an act which could be considered simular to suicide, but Kenzaki finds another way. Both of these also count as attemptingHeroic Sacrifice, as he was trying to save the world in the process.
Black Mirror has an odd one. After kidnapping a member of the royal family, getting the UK in an uproar and blackmailing the Prime Minister to have sex with a pig on live TV he decides to kill himself. Seems it was all just a big stunt and presumably he killed himself to avoid capture although he might have got away with it...his suicide and motive is never properly explained.
The series 2 episode White Bear opens up on a failed attempt on this, presumably she attempted to take her own life after the mysterious broadcast made everybody turn nuts. Well actually she didn't attempt to commit suicide, that was a set up. Her boyfriend did though and she really does wish for death by the end of the episode.
On Sherlock, this was Moriarty's plan for Sherlock.
On Glee, Dave Karofsky tries to kill himself after being outed at his new school, then viciously bullied there and on Facebook.
On Justified, Mags Bennett poisons herself at the end of Season 2 because two of her three sons are dead, and she hates her only remaining son.
On an episode of Emergency! Gage and De Soto are are called by a woman whose roommate has taken a bottle of barbiturates. When they arrives, the woman is conscious, and refuses treatment. The roommates begs them to do something, but they tell her as long as the woman is conscious and refusing treatment, they can't intervene. Once she passes out, they can try to revive her, but by then, it may be too late. While the woman is still conscious, she explains to them why she's been driven to suicide by all the horrible things in her life, none of which are very bad, just to make the point to the audience that suicide is a bad choice. Gage and De Soto had their equipment ready, in the woman's room, watching her become less and less alert until she passes out on her bed. Then they give her oxygen and drugs to counter-act the barbiturates, and rush her to the hospital, but she dies anyway. There's a not-so-subtle PSA regarding the right of a conscious person to refuse treatment. It was a concern a lot of people had with the new profession of paramedic. There was also a sub-textual PSA that went something like "Don't say 'No' to a paramedic!"
In the Spanish series El Internado, Fernando tries to kill himself, so that Amelia doesn't have to work for Camilo and Noiret to keep him alive anymore. He succeeds on his second attempt, driving a car off a cliff.
Elsa tries to overdose on pills after she miscarries and Hector divorces her.
Tommy from The Shield shoots himself after having his ex-wife and son murdered and losing his job.
Subverted in Sons Of Anarchy when the incarcerated Otto - who had nothing going for him - slashed his wrists. It was later revealed that not only did he not succeed, but he never meant to - it was a gambit to get into the infirmary in order to kill the man who tried to kill Jackson.
Juice tried to kill himself and it really looked as if he succeeded until the next episode revealed otherwise.
An episode of The Pretender involved Jarod investigating the suicide of a military recruit who was given an experimental drug that brought about an intense feeling of despair. As usual, Jarod gave the man responsible a taste of his own medicine (literally in this case), but also as usual, stopped short of killing him - he gave him a reduced dose that was enough to make him cry like a bitch for a few hours, but not enough to make him take his own life.
Julian at first seems remarkable nonplussed about killing Jessie, but he does eventually become disgusted with himself (and with the others who helped him cover it up) and leaves a confession behind when he kills himself.
Subverted in the pilot episode when a patient was brought and everybody assumed it was an attempted suicide by crushing a car. However, she's soon diagnosed as having a stroke and that it was an accident.
One patient is brought badly hurt, and everybody assumes he was a jumper because he was found under the window. The team are reluctant to treat him, but they do nevertheless. He might end up an organ donor but they actually need organs for him. The team's attitude change when they find that he in fact did not try to commit a suicide, but was pushed. Dr. Hooten calls them on it later and is extremely harsh on them, because suicidal people are considered ill, not losers unwilling to live. Well-played, Dr. Hooten.Jerkass Has a Point in this series for a reason, and he was not a jerkass at this matter at all.
Never Wipe Tears Without Gloves: Bengt after getting his AIDS diagnosis. Paul in a moment of Gallows Humor bitches about the unkindness of not letting the disease waste him away but leaving a heavy body for his equally sick and weak friends to carry when they served as pall-bearers at the funeral.
Everwood: Reid, Ephram and Bright's room-mate from season 4 eats pills and is found unconscious when he flunks out of medical school. He couldn't deal with the amount of work and cheated on a test, got caught and was expelled. His friends all feel guilty for not realizing that Reid was depressed. Upon recovery, Reid pretends everything is fine which understandably upsets them and Amy calls him on it.
In the Heat of the Night had one where a young beauty pageant contestant takes sleeping pills when her secret past of drug use and pornography comes back to haunt her. Another episode had one where a respected teacher was falsely accused of sexual abuse by a student who was upset about being disciplined by said teacher over a classroom prank. He was cleared but was found dead in his car from carbon monoxide poisioning when Tibbs comes to tell him the news.
