Hello Chargedupray: I see this is your first post here on PC. Welcome to Psych Central.
We here on PC cannot offer mental health diagnoses. Plus I'm not a mental health professional. (Most of us here on PC are not.) So I can't suggest anything with regard to what may be going on with your friend. You mentioned he was taken to a psychiatric hospital a few days ago. The professional staff there are the ones who are going to have to figure out what is going on & what treatments may be appropriate. Perhaps other members, here on PC, may have some thoughts they'll wish to share regarding your friend's situation though.
I hope you find PC to be of benefit.
