Occurs a good number of times among the inmates in Oz and Prison Break.
Arrested Development: Tobias Fünke has three of these in one episode after his wife Lindsey gets the first acting part he tries out for. Unfortunately he also missed the call telling him that Lindsay hadn't shown up and he had got the part because he was in the shower at the time. He also received a bad review from the school paper for the high school production of A Midsummer Night's Dream he directed. Cut to Tobias weeping in the shower wearing cut-off jean shorts. It isn't the only time.
General Hospital: Liz Webber is shown crying in the shower after Lucky brings her to his house to comfort her post-rape.
Brenda, after sleeping with her friend Miguel a mere two days after breaking up with boyfriend Sonny.

Buffy takes a particularly hard fall on patrol and goes to take a shower to soothe away her aches and pains. This plan goes awry when Spike accosts and tries to rape her. However contrary to the usual she doesn't actually use the shower.
"I Only Have Eyes For You". Angelus is possessed by a ghost and forced to act out a tragic love affair with a similarly-possessed Buffy. He's seen afterwards vigorously scrubbing his body in cold water and complaining about having been violated.
Angel: After Faith gets the crap beaten out of her, she showers off to clean up the blood. Then she vents her frustrations on the shower tiles.
Male version: Shirtless Scene ALERT! Davis does this in season 8.. to show to the audience that he's an indestructible monster or something... (which would possibly make it a Draco in Leather Pants moment but that's a different story)
Dark Angel has one of these with Max, in the episode "meow", after she has sex with a random guy to sate her literal "cat heat" and afterwards cries in the shower because she wanted it to be Logan. Considering Jessica Alba is involved, it is surprisingly tastefully done, mostly focused on the shoulders up.
A male example after Ballard has sex with Mellie/November one last time.
Adelle DeWitt takes one of these in episode 2x09 in an attempt to sober up and regain control.
Cracker. DS Penhaligon takes a bath after she's been raped, but makes sure to wrap her hand in plastic first to preserve evidence from when she scratched her attacker.
Jay Leno played this for laughs in his version of The Tonight Show. Leno mentions something Squicky in a monologue — cut to a (mercifully) tight shot of him in the shower frantically scrubbing his chest and saying "EwEwEwEwEwEw".
Carrie has an angsty shower in the episode when she turns 35 and everything is going wrong, to the point where she drops her own $60 birthday cake in fresh tar, in front of a couple of fat construction workers screaming at her to move herself out of the way. Wonder she didn't drown herself.
One of Miranda's guys-of-the-week does this after sex with her, which kinda bums her out. When she attempts to empathise with him, her assumptions about his Catholicism offend him and he storms out. Carrie muses that the dialogue of this fight finds its way into a play he was writing.
The Scrubs episode "My Cold Shower" has a recurring gag of showing the characters taking cold showers, although these are moreso caused by sexual frustration and played for laughs. But JD's last cold shower in the episode's final scene acts as a true Shower of Angst, as he realizes that he still has feelings for Elliot right after she accepted Keith's marriage proposal, with JD realizing "It should have been me." and then he looks at the camera
An episode of CSI features Catherine Willows waking up half-dressed and disoriented in a cheap motel. She takes a shower—after improvising a SAE kit to run on herself. It wouldn't be admissible in court, but she just wants to know, one way or the other.
An episode of The Drew Carey Show has Drew taking one of these after realizing the woman he just had cybersex with was Mimi. He was fully clothed, though.

Lampshaded somewhat on Friends when Joey gets an acting gig as Al Pacino's 'butt double' in a shower scene in a movie, and manages to overact the moment:
Director: And cut. Hey, Butt Guy, what the hell are you doing?
Joey: Well, I'm—I'm showering.
Director: No, that was clenching.
Joey: Oh. Well, the way I see it, the guy's upset here, y'know? I mean, his wife's dead, his brother's missing… I think his butt would be angry here.
Director: I think his butt would like to get this shot before lunch. Once again, rolling… water working… and action… (Joey does the scene again) …and cut. What was that?
Joey: I was going for quiet desperation. But if you have to ask...
Overlaps with Shower Of Gayngst in ER: Kerry Weaver, pre- and post-date with Kim Legaspi.
Played for laughs on The Colbert Report where a reporter was promoting "Voter Abstinence" (a promise not to vote) and was pretty much doing a sexual abstinence PSA only using "voting" as an Unusual Euphemism. He said that he'd been "tricked" into voting for a candidate that he thought had his best interests in mind, but once he was elected, he abandoned those who'd elected him. He was then shown crying in the shower as if he'd been raped and was trying to get himself clean.
The first season finale of The Walking Dead has the survivors find temporary shelter, complete with hot showers. Most of them enjoy it, but Shane carries a wine bottle in there with him and breaks down sobbing. Of course, he's carrying a lot of angst by this point. Andrea is in a fetal position, since she had recently mercy killed her zombified younger sister.
There's a second one with Shane in season 2 as well, after he shoots Otis and leaves him to be eaten by walkers so that he can escape. He also gets an Important Haircut after the shower.

In the Witchblade pilot, Sarah takes one complete with fetal position after nearly getting killed in a shootout with a hitman. Her inner monologue communicates the angst quite nicely:
I don't know why I keep pushing the envelope. Something's gotta change. I've gotta change.
On Glee, Blaine is briefly seen taking one after being forced to confront his rough relationship with his brother. Also a case of pure Fanservice.
Finn is also briefly seen taking one in another episode after a fight with Rachel, complete with him banging his fists against the wall.
Implied in the pilot episode of Monday Mornings. A Littlest Cancer Patient — a truly cute child — dies on Dr. Ty Wilson's table. He's got all bloody and feels obviously shattered. He wants to go to talk to the kid's mother, but Dr. Ridgeway tells him to get a shower first and change his scrubs, which he does and returns clean. (Pity the audience didn't get to see it because Dr. Wilson is played by Jamie Bamber.) Quinn's death gives him a Heroic B.S.O.D. because he later finds out he made a mistake by not checking all relevant medical history.
In an episode of 21 Jump Street, a pastor's son feels so ashamed of touching a girl in his teen Bible study group that he goes into the river and frantically tries to "baptize" himself to wash away his sin.
In another episode, Officer Hoffs plays this trope straight when one of the characters in the case she was working on rapes her.
In Empire, Andre—who's secretly bipolar—suffers a manic episode after his father Lucious reveals he's dying of ALS. It begins with him throwing a tantrum in front of his family and abruptly leaving with his wife Rhonda, and ends with him in the shower, fully clothed and hyperventilating.
In The Following, Ryan is fond of these. A particularly notable one occurs after he fails to save Jeffrey Clarke and finds his mangled corpse in a box.
On Magnificent Century, Sadıka takes one after being raped by Süleyman. It's truly heartbreaking.
