"His mom is dead, his dad was missing and presumed dead, heís running around with a military organization... itís not exactly conducive to therapy ó and, of course, because itís TV, therapists donít exist."
Dysfunction Junction: For stories (or works) where a main plot of the story is that those entire characters being cast are crazy.
The Shrink: If a character does go to a therapist but the therapist is unskilled, condemnatory, or otherwise problematic, see The Shrink; versions 1 and 2. If this trope is averted when the character goes to a good therapist and gets the help they need, see The Shrink; version 3.
Unintentionally Lampshaded in Rebuild of Evangelion when a character comments "those kids are our last hope, who knows what they're going through?", many Humongous Mecha series feature characters who clearly have flagrant psychological issues which are inexplicably overlooked so long as they are good pilots, which naturally never lasts for long. To make things worse, the EVAs only work if the pilots are horribly dysfunctional and emotionally messed-up. Even if there are a few therapists left, NERV wouldn't let them anywhere near the poor kids.
Parodied in What If? v2 #2, where Daredevil murdered the Kingpin and went insane with guilt. While he's running around, he bumps into the Punisher. When he sees just how broken Daredevil's become, Castle actually recommends a psychiatrist and offers to take him there personally.
Justified in The Walking Dead; so far, no member of the group past or present has been a therapist. For all we know, there might not be any therapists left.
Sometimes I wonder whether it would be easier if I just had Shizuru see a psycologist. The problem being, how does she say "I have a huge guilt complex over killing scores of people with my summoned demon named after the legendary Kiyohime" without being put in an asylum? Perhaps the First District has specilised psycologists. Oh, wait. She blew them up. That's what she's guilty about.
Played with in every way in Bujold's Vorkosigan Saga. The main character is from Barrayar, a feudal militaristic culture where one is expected to go through hell and get over it without complaints and definitelywithout therapy, but his mother is from Beta Colony, a high-tech hyper-sophisticated and modern world where all is well-regulated and therapy is the normal response to any trauma or psychological issue. The trope is inverted in the first book for both worlds: Cordelia's awesome Betan therapists refuse to believe she is actually sane and wasn't brainwashed into falling in love with the enemy and she ends up having to run away, while it's revealed that Barrayaran therapy of the kind Bothari went through is possibly worsethan the original trauma. In later books the trope is played straight (and Lampshaded by Cordelia repeatedly), especially where Barrayar is concerned. But it is thankfully averted for Mark after a book or two, because he reallyREALLYneeds it.
There seems to be no psychiatry in Harry Potter. Harry went through hell in his school and was obviously suffering from PTSD in the fifth book, but nothing is done to help his psyche. Especially bad considering the death and torture he watched and experienced was then lied about by officials high up in the government.
Live Action TV
Some police procedural and military themed series try to avert this trope with special episodes focused on the main characters being forced to attend mandatory counseling sessions to determine whether they are fit for duty.
Averted in Garo's first season, and justified in the sequel. When Kaoru dreams about her father's picture book at the start of the series, she regularly visits a therapist who helps her to explain this dreams, and helps her with the weird things she suffers since discovering the existence of Horrors. The justified during the second season comes from the fact that the therapist was actually the big bad of the first season and tried to sacrifice kaoru to bring the end of the world, which explains why she may not have desire to try therapy any time soon.
Completely averted by Mash, in which Sidney Freedman is a recurring Type 3.
Ditto Red Dwarf, millions of years after therapy has ceased to exist. Kryten in particular has expressed his wish for a "really world class psychiatrist".
A surprising aversion in Series/Continuum. Mostly, there's an implied All Therapists Are Muggles in play; the protagonist is from the future, so if she tried to talk about her problems, she'd get locked in an asylum. That's exactly what happened to another time traveler (though in fairness, he really was crazy, as evidenced by the fact that he didn't see anything wrong with chatting about being from the future). The aversion comes into play when Kiera strikes an officer in anger, and she finds out that her cybernetic Augmented Reality implant has a therapist AI built-in. He's briefly an inversion of All Therapists Are Muggles; he doesn't believe that they're really in the past and assumes she's had a psychotic break, but when he can't contact headquarters, he tables that issue and moves on to her real problems.
Averted on Friends. Ross see's one when he's struggling with anger issues and both Chandler and Monica mention that they've been to therapists and even discuss it in one episode.
Chandler: I hate having to see the shrink. He's always 'oh maybe people will like you better, if you like yourself better'. Who needs that?"
Monica: You do!
Chandler: I know.
Averted on The X-Files: Fight the Future; therapists of varying kinds are seen. Scully sees a therapist at least twice to discuss her problems. Mulder sees one to be hypnotized into remembering the events of his sister's abductions, and eventually takes Scully there to be hypnotized into remembering one of her own abductions.
Quadrophenia features the overlap with Adults Are Useless. Jimmy asks a therapist, vicar, and his mother in the very second song, but it doesn't do any good.
This trope is literal in Furcadia as psychology has not been invented yet and magic generally only heals the body and not the mind. Several of the gods in this setting are also insane (oh, and like to wander among the mortals...).
Parodied in Alpha Protocol if Mike is played as a brutal, violent Jerkass to Madison. She'll ask him if he has ever sought professional help. He replies that he hasn't, because he killed all his therapists.
Key to the plot of Kinder; a running theme is that 'mind illnesses' are not recognized as a real problem in its world, instead attributed to things like "they're just lazy" or "they're just complaining for no reason." Naturally, this causes major problems. Yuuichi eventually states that there's probably worlds out there were 'mind illnesses' actually are recognized and treated more seriously.
In Something Positive there are many cases of this, sometimes lampshaded, but the one that stuck out most for me is when Davan never gets help after being raped by a woman he was attracted to. Sadly this is probably Truth in Television for many rape victims, especially male ones, and especially when the rapist is a woman.
Played with in Homestuck. There are no therapists, but there are plenty of amateurs, Rose and Karkat in particular love to psychoanalyze the other characters, and Karkat even gives out relationship advice for the other Trolls.
Mild subversion in Karkat's case in that Karkat is a film buff like John, only where John is into cheesy monster flicks, Karkat prefers romantic comedies-and his species defines four different relationships as forms of romance. So all his relationship advice is coming from his movie-watching habits rather than his tendency to psychoanalyze, and is thus dubious at best.
Rose is hardly better, since her own analyses tend to take the darkest, most complicated explanation possible, and she refuses to even acknowledge any other explanation. At the start of the comic, she believes that her mother affects Rose's own interests in sarcasm to mock her. Dave suggests the ironic alternative that Mom might actually have the same interests as Rose. He's right.
Played with in Spacetrawler. The I.A. Starbanger does have a Therapy-bot, but he's terrible: his therapy consists solely of telling patients that their feelings are irrational. Eventually, Martina realizes that one of her crew desperately needs treatment for post-traumatic stress disorder, so she replaces Therapy-bot with a qualified therapist.
Zig-zagged in A Loonatic's Tale. There are, in fact, therapists, they're even major characters in the comic, but they have a whole host of psychological issues all their own which may or may not prevent them from actually doing their patients any good (at least one is too apathetic to do his job, so he just medicates them into oblivion). On top of that, most of them reckon that, since they're therapists, they're immune to psychological disorders, and wouldn't need help even if they weren't.
Averted with a vengeance in Material Girl. As the story gets darker and the Cerebus Syndrome kicks in, Noah's parents go from joking about taking him to a therapist to forcibly strapping him into the car and dragging him to one.
The Nostalgia Critic used to mention going to a therapist a lot, but that stopped, probably because the character was getting more and more damaged and it was funnier that way.
In fact, a running gag among multiple reviewers is their constant danger of insanity due to the bad things they are "forced" to experience. Plenty of reviews have gags where the reviewer pops "happy pills" like they were candy, chugs from a bottle of booze, or is forcibly restrained by men in white coats. Some have even tried to destroy the world in a bout of rage. Spoony deserves special mention as a full-on insane convicted serial killer.
Defied in Worm when Weld specifically requests therapy for the Brockton Bay Wards.
Played with in Winx Club: The Trix are sent to a place where they are supposed to be reformed, but it only manages to tick them off even more.
Lampshaded in As Told by Ginger in an episode where Ginger becomes jealous of Darren's new relationship with Miranda. Of course she didn't technically see a psychologist.
Ginger: "It's just that Dr Phonsfeelings said—"
Darren: "Whoa, you went to see a therapist?"
Ginger: "Not exactly. She was on Channel 9"
Said TV psychologist appears in another episode and causes more problems when Ginger starts freaking out that her mother is still single.
And inverted in another episode where Ginger is sent to the school psychologist because she writes a poem about a girl who wishes to disappear. Everyone assumes Ginger has suicidal intentions because of this but she's actually fine.
Zig-zagged in Young Justice. Black Canary is a trained therapist, and is shown having sessions with the teens after seriously traumatizing events. When Arsenal begins to suffer from serious issues that have interfered with their missions more than once Nightwing benched him which is pretty much the same as telling him he's off the team until he can deal with his personal demons.
Zig-zagged in Adventure Time. Ooo is a very strange place with a lot of even stranger people, but there actually are mental health services for those who need them. For a lot of the earlier episodes, however, this trope was played straight, with people such as Lemongrab and Ice King basically just being dealt with when they caused trouble and ignored when they didn't. Both of them have now been getting a lot more help.
