My advise is to be honest. Your therapist can't properly help you without knowing the whole story. When it comes to the half-hearted attempt, if you don't want to tell him, I get that but I doubt he'd put you in the hospital since it's happened so far in the past (unless I'm misinterpreting this and it was recent, then I think you really do need more intensive care). When it comes to the meds, they could've very well made it worse, you need to tell your doctor asap so that can be managed. This is a good and safe place to talk and I'm glad you're talking here, though I wish you weren't hurting so bad.
