I find it really hard to imagine that any T would say something like "God, I can't stand you" to a client, especially without any provocation. I agree with the others that you need to consider that what you're hearing isn't accurate.

Rather than firing your T, you should probably talk to her about this. She may be able to clarify what she actually said, and she may be able to help you with your feelings around this, about trust, etc. It sounds like a very difficult experience.
