I would suggest sharing the anger with your t. She would probably want to know how her words made you feel and can help you explore how that lead to your tailspin.

I went through that with my t not too long ago. I was upset with her, but never expressed it during that session. I waited an entire month to say something. It lead to a long discussion about me being comfortable enough to express anger with t. Instead of hurting the relationship, it strengthened the relationship. T assured me I would not hurt her feelings by expressing anger.
