Might I suggest that one important thing here is going to be for your son to have some sort of program to go to once he's released from the hospital? I know that, in my own case, those first few days & weeks after having been in the hospital, were challenging. One time I did end up attending a partial hospital program & it helped. It wasn't even that the program itself was especially great. But it gave me somewhere to go & something to do at a time when I was adrift.
