My personal opinion is if you cancel you wont grow. If you hide from him what is you what is your fears and insecurity you are not giving him a chance to be your therapist. If you only let him see what you think he wants to see or what you wish you were then he cant be helpful to you. Tell him your feelings about wanting to hide from him. Write it down if u have to. You can heal the part of u that is afraid and by being true to yourself you are actively participating in therapy. What would be the point of going to therapy and never allowing him to see this fear this pain that is most cetianly triggered from your past. He needs to see that child in you so he can talk to her. SO he can help her. By helping her feel secure he will be healing that fear.

P.S. If my therapist ever read this post I wrote to you, she would break out the champagne. She has been telling me this forever. I just roll my eyes at her. So dont tell her ok? Plus it shows u giving advice is easier then actually utilizing it.
