It's Kind of a Funny Story (2010)

Stressed by adolescence, 16-year-old Craig Gilner checks himself into a mental-health clinic. Unfortunately, the youth wing is closed, so he must spend his mandated five-day stay with adults. One of them, Bobby, quickly becomes his mentor — and him his protege, while Craig finds himself drawn to a fellow teen, Noelle, who just may be the cure he needs to forget an unrequited crush. Starring Keir Gilchrist and Zack Galifianakis, It’s kind of a Funny Story is based on a novel of the same name.
