Question

Why does Craig recover so quickly after his stay in Six North in the movie, "It's Kind of a Funny Story"?

Answer 1

To take an alternative explanation, Craig spends much of the novel feeling trapped in toxic environments. He takes the choice, at Six North, to free himself from a stressful school, and his rapid transformation may reflect the release that comes with finally eliminating this burden

Answer 2

Because he had a friendship of his cousin.
