I know it is difficult to build trust. EMDR T is not your old T. Try to give her a chance though. In time, the more you are able to share the more she will be able to earn your trust. You will never know how she will respond umril you try. You may want to start by explaining how other T understood what you meant.

I know it is not easy. I have been seeing my T 2 times a week for almost 2 years and I still don't totally trust. He knows it and he knows why based on my background. He always reminds me to not trust him any more than I feel comfortable with. We do EMDR as well and he knows I hate it.

Good luck and hugs to you. Give it time.
