(((Inny)))
I have dissociated so often in therapy that I swear my feet have never touched the floor there.
Please don't let that experience deter you from getting the help you want. The right therapist will not be put off by your dissociation, but will want to help you. I am now at the point when I can tell T that I am starting to drift.
Yes, it's painful, nerve wracking and all those things, but there is hope for a real grounding ahead, just stay the course.
