Granite, I agree with Sannah. I think you have problems with therapy, with communicating, with fear about feeling exposed, with trying to mind-read what the therapist thinks about you (which has never proven to be accurate). I don't see that these problems will go away with another therapist. These are issues you are going to have to face and work through with whatever therapist you see.

It seems like your therapist has a better understanding of you than you are comfortable with. That scares you and you want to run. But all that is going to accomplish is starting with another therapist that you will still have trouble communicating with, you will still try to mind-read, you will still feel exposed as soon as a new therapist starts to get a good understanding of you, and you'll want to run from that therapist too as soon as you feel this way again. Aren't you tired of running?

You are scared right now because your T has a better understanding of you than you are comfortable with. That seems incomprehensible to you, you feel exposed, and you probably feel scared and a bit unsafe because these things about your life have remained a secret for so long through your silence. You have a T who has patiently worked with you, who has tried and utilized many different methods to help you communicate, who has remained constant with you through this process, and that consistency and care and patience and insight scares the dickens out of you.

Rather than go to another therapist and taking all of this with you just to repeat this whole process again, how about considering telling your current therapist how scary this process is becoming right now, how feeling exposed feels dangerous to you, how you want to run from it, how her insight into your history frightens you? I suspect your therapist, as she always has, will listen attentively, understand deeply and with great care and compassion, and find a way to help you through these fears.
