I commented in your other thread that your situation sounded a lot like mine... Now it REALLY sounds like mine.
My previous T attacked me in the same way yours did, though she did it in person. I begged her not to terminate me in almost exactly the same way you did - complete knee jerk reaction and I was utterly thrown. She threw me out of session and I still have no idea exactly why, though she later admitted countertransference.
I went to my next sessions determined to confront her and figure out what happened and what I did, but like you I melted in the room and lost my nerve.
It's scary some of the things she is saying to you - it's almost word-for-word what previous T told me - rude, disrespectful, not going to take abuse from me etc. not to mention that I felt like the whole thing came out of left-field and I had no idea what was going on.
I have no idea what to tell you. The 'repair' in my case was a band-aid at best. I hid behind idealization and ET for the remainder of my time with her. In retrospect I feel like I hid myself and my upset and did my best to keep her happy. She ended up terminating me because she didn't feel that she was able to help me.
I would say turn around and run as fast as you can, but I know how much doing that will hurt...

ETA: This one really hit a nerve. I'm shaking like a leaf
