It sounds like she is basically saying "your therapy isn't helping me." The thing she might not get is that you (probably) don't go to therapy to work on becoming who she wants you to be. Is there any reason you have to discuss your therapy with her at all? Is it important to you to make her understand you?

Speaking only for myself, my life improved a lot once I stopped trying to make my parents understand me. I realized at some point that therapy was fulfilling my need to be understood and so I was liberated from having to seek it from such unlikely places anymore. It took awhile longer to realize that I actually no longer care so much if my family understand me. Our relationship has improved tremendously since I'm no longer hoping for something they cannot give.

I wonder if it would be helpful to just go with some variation of "okay thanks, I'll think about it" or something when she starts saying anything unhelpful. You can choose not to engage when people criticize or undermine you. Subject changes and leaving the room are also good strategies.

Telling someone that they're hurting your feelings is only worthwhile if they a) care about your feelings b) have the ego strength to hear you without being defensive. When those conditions are not met, IMHO, you're best off just shutting down the hurtful conversation.
