I have been in the hospital a few times - twice to adjust meds, once after an OD and the last time I took yield because I was feeling very suicidal.
My hospital stays have been positive. I see my pdoc and T daily (except Sundays). Group therapy is not compulsory - I went once and hated it.
They also had a LOT of food... Otherwise I generally slept. For me it helped that they could medicate me to pretty much knock me out for 3 days until I got over the worst of my suicidal feelings. It was the safer option.
