From this thread, it sounds like you feel that therapy may not be entirely useless for you? Or at least you have some level of desire to stay, even if it is not positive but quite ambivalent? From your posts on this forum, you most definitely don't sound like someone who only looks at things superficially and from one angle in spite of C and whoever else is involved. I have no experience with what you seem to be dealing with but I imagine perhaps I would ask, what would be the risks, what sorts of things would be against doing more of this therapy, other than discomfort? Given that right now it sounds like it's hard to predict potential benefits for you.
