Would you be able to talk to him some about it? At least enough to be able to go to him in a crisis... He doesn't have to understand to be there for you... If not, that's fine, my own mother barely knows, short of that I went in for being suicidal, and now I go to therapy... And I still wouldn't go to her... But I think it may be useful to, if nothing else, get a game plan with him as to how to handle that situation if it comes about... I would talk to your therapist and see what their opinions are of meeting you at the hospital and whatnot... They may have some better advice than me for you...
