I have various pains from physical stuff that's becoming more of a problem, on top of being bipolar ... so I can relate on some days to how you're feeling. No bf, though ... just me and my cats.
if your T is offering hospitalization, why not give that a try? They'd have a chance to seriously re-evaluate you medication, top to bottom, even do a nutritional study ... Might turn something up that could lessen both the pain and the depression. Can't do most of these out-patient.
Consider it a vacation from the people and places in your current life. If you've lost interest in this life, what have you got to lose?
It would also show everyone that you were willing to make one final effort. I hope you'll give it some thought.
