I have walked away from therapists that made me mad or scared me, and I can understand wanting to reject your T before he or she has the chance to abandon you. Isn't that what we keep doing over and over in real life too? But I hope that you will give yourself the chance to find another T who can help you to finish your healing. If you quit now it would be hurting you much more than the T. Yeah, I think I would cling to those last few offered sessions, and maybe ask what if I refuse to leave. But I would accept what is offered.
