I'm sorry things are so tough right now, and sorry that you don't think your T is getting it. I think it may be possible that she's getting frustrated by all this negative self-talk. It's hard to hear people say that they're horrible when you know it isn't true. You're not horrible.

Maybe it would be helpful to tell your T exactly what you need from her--support, empathy, not advice and judgement. Hope it gets better.
