Wow, sounds like a really hard session.

It also sounds like your T was trying a tougher technique to see how you would handle it/respond....and perhaps this processing and your later reaction is really important! It might be worthwhile for you to document how you're feeling and bring this in to your next session to discuss it with T.

My T tried to be tough with me during another occasion and he said something that I felt was very hurtful. I addressed it at my next session, and he told me he was trying to shock me. He felt bad for being mean by saying what he did, but he was feeling a bit desperate at the time because he felt I was in danger.

It seems that your T already said she was pushing you. But it would be worthwhile for her to know how you reacted to that pushing, during your processing of it. Because it may not be a technique that works for you.
