She may be giving you the opportunity to reality-test the situation. Maybe she is waiting for you to ask "Are you mad at me right now?".

CBT T did this to me---I said I thought he sounded angry but then he said "Did you ask me what I was feeling in that moment?" Um, no I didn't think to ask. Once I did, he said he was concerned not angry. But sometimes when they let you know, it CAN be hard to believe. I tend to think T is angry even after they say otherwise.

I get your dilemma and understand why it feels sadistic. T understands the outside world won't adjust to your triggers, but you CAN ask questions to find out if your assumptions are true or not.
