Welcome back to the forum. I'm so glad you're feeling better.

No advice here. I think, based on the past threads and concerns you had, and the anguished back and forth, it's really important to trust your own instincts. I think you have good judgement and just need to nurture it.

I do believe that you won't have such a rough time in therapy if you see a better, more boundaried therapist, for what that's worth, so no, it won't be a repeat of the wrenching/exhilarating/hurtful last round.
