I guess I'd try to find a local schizophrenic support group in your area and get a feel for resources and see if there were others you could move in with or a good group home, etc. I'd find somewhere else that was "mine" but if I wanted to help my father as much as I could you could make that your "job", be his companion and make sure he isn't drinking/able to get alcohol before you leave each evening, etc.? But I'd start to make my own life so if/when he has a problem so he's not able to be on his own you'll be better supported and able to cope and have a life of your own so it won't be quite so drastic a change?
