Hi Rio!
I do not know that there's alot you can do for him, but just being there to support him. It sounds to me like it's out of your field. He needs professional help right away. Have you encouraged him to seek medical attention? He needs to very quickly. There are places you can go that offer free services if you don't have insurance. I used them back in the 70's when my husbands ins. didn't cover Psychiatric treatments. It sounds to me like your friend is in a chrises
that he shouldn't handle by himself. Try encouraging him to get immediate attention. It's imparitive that he get help
now!!!
Good luck.
