Some great feedback on this thread. Thanks everyone who offered their insight.
I haven't posted in awhile because we've been anxiously waiting for my son to meet with EASA (Early Assessment & Support Alliance) to see if they will accept him into the program. These are specialists in teen/young adult first psychosis situations. They stress relapse prevention/management and life goals.
We met yesterday and today I got the call I've been waiting for for several weeks. They will take him!
So through this program (http://www.easacommunity.org/) he will get an in depth assessment/diagnosis, one-on-one therapy, support to start up his life again, etc. I feel absolutely blessed that a program like this is available and that he both qualifies and is interested in continued therapy. The age restriction is 25 and he is 24, so a close one there. He would have been disqualified if the psychosis was completely drug induced or had happened over one year ago.
I do believe he will continue to improve and at least to some degree, steer his life toward perhaps a job and independence again. If he relapses during his two year time with EASA, they help him/family through it. There is also both family and peer-to-peer support.
Things have been slowly getting better and the bad days are not as often. Though yesterday my son and I got into a bit of a tiff. He blew up at me because I said an internship at a computer store would possibly help him obtain a job he liked. He stomped upstairs and then I about fell over when he came back downstairs, APOLOGIZED to me, said he loved me and asked for a hug. I was just blown away. He has a long, long way to go but this moment of insight was real progress.
I am feeling sincerely hopeful for the first time in a month.
