I guess what I would say to you is that all of us have an innate wisdom about what is right for us. When I make decisions, I feel whether they are right for me, usually after I make them. I know I've made a good decision when I feel a sense of release and freedom.

So, from my own experience, I'd say that if you feel this way after quitting, then maybe it's not the right decision for you. It might be the right thing to seek a different therapist, but I thik that maybe you need to slog through some more therapy to get to a better place.
