I have negative transference, too. There's an attachment pattern where you feel bad about yourself but hold others in high regard, which explains the cause. In my case, I internalized it from my mother. It is transference, but reflects my sense of self as it is magnified in therapy.

The only thing that leaves me questioning is that I didn't have this problem with other therapists. But like you, I've had it in another close relationship before. But he wasn't trustworthy by any standards.

Does she say positive things about you at all?

I really don't know how else to deal with it besides talk about it over and over and hopefully believe in yourself some day. You sound like you have a lot of guilt and shame. That might be where it comes from.
