In my opinion, your T isn't using the right methods to foster self-worth. He may not be the kind of T you need. I am reading Attachment in Psychotherapy, by Wallin, and learning how a T can use the relationship and especially non-verbal cues from the client, to cause changes. It's not just talk therapy; it's the relationship that makes a difference.

My T is attuned to my non-verbal cues and we discuss how I feel in the present moment in the therapy room with her. The relationship itself builds up my self-worth. It's in the little things, her praise of my artwork, of the cookies I bring her, the way I'm coping with my life now. It's a process. I don't think I'm explaining it very well. It's something I experience with my T, kind of like re-parenting. I think that would be beneficial to you, but it doesn't seem like your T works that way. He should be making you feel better about yourself, not causing you to feel shame. The goal is for your relationship with your T to be different from the one you had with your parents, not the same.
