What if you don't agree about a core belief?

There are things about me that make me feel I am bad. L doesn't think I'm bad for these things. There are also things I've done that I feel are bad. L says she doesn't know enough about the topic and how I perceive it to determine whether she feels it's bad or not.

I want her to tell me I'm bad and what I did was bad. I want her to agree with me. I feel like we're in different realities if she doesn't. I feel that she doesn't understand or maybe even not taking it seriously. That she's falling back on her therapist role of being neutral. I don't want neutral! I want her opinion as a fellow human being.

What I did has to be wrong. It can't be right. I'd ask her to go research it, but there's not much research out there.

So have any experience with this? What do I do when L disagrees with a core belief about myself? I feel stuck.
