Can't encourage you enough to share everything, and I mean everything, with your therapist. He cannot do his job properly if you don't. I have strong feeling that this will be the thing that helps you get unstuck. Therapists cannot help people who don't open up to them.
I know it's scary, believe me. I had some unbelievably scary moments in therapy. But, I'm so grateful for having that person and that place to help me through the fear. It made such a difference in my life.
