Well, if all of your therapists, 6 or 7 or so, have said the same thing, then maybe there is something to it.

Sounds to me as though you are missing a lot of opportunities to learn something about yourself and what you are capable of. I think it is quite hard to treat depression as independent from lifestyle, and an overhaul of thinking may be required to help you to feel better.

Part of therapy, I think, is letting go of preconceived notions and opening your mind to something different.

Close off nothing, anything and everything is possible.

It won't be easy for sure, in fact, in may outright suck, but maybe it's a shot, and a good one, at a better life - or at least symptom relief.
