I think you answered your own question about hospital: no. It won't work for you, unless they are going to adjust your meds and make a long term plan for healing with you. I agree, some ppl get worse in hospital settings.

Now, about the residential.. when does that happen, and how far away, and what age group will you be in with... and why not give that a try, you might find it gives you support you sound like you really need!
