A T can still be human and not bring themselves into the therapy session. It's not an either or situation, a robot or a human... there is a middle. And yes it's acceptable for a therapist to point out if you're speaking to them unpleasantly, but they have to keep their own feeling out the room, ie not be led by their emotions. So if she feels annoyed she needs to notice that and file it away for her own therapy or supervision.

But i see what you're saying, that this is more about how you felt rather than anything she did?
