It's Kind of a Funny Story (2010)

Craig is a high-school junior in the gifted program, infatuated with his best friend's girl. When he realizes he's suicidal, he checks himself into the psychiatric ward of a hospital, thinking they'll do an observation, help him, and send him home in time for school the next day.

Once in, however, he must stay for a week; the juvenile ward is being renovated, so he's in with adults as well as a few youths. Bobby, a man with a young daughter, shows him around; Craig notices Noelle, about his age. He tries to keep his friends from finding out where he is. He draws, goes to therapy, sings, helps Bobby rehearse an interview. Is this the stuff of insight?
