It's hard to say what I would do in your situation without knowing exactly what boundaries she was crossing.

If for example, your current therapist is sounding like your mother and you are angry about that, then the only thing to really do is to tell her about your anger. If you state it reasonably calmly and she still responds defensively, then you might want to consider transferring therapists.

On the other hand, she touches you in a way that you don't want, or does things like show up at your house or call you in the middle of the night, those are clear ethical boundaries that should not be crossed. In that case I would report her to her ethics board.

If you have trouble telling if this is just a "bad fit" or actually an unethical therapist, and you are uncomfortable posting any details, then you could make an appointment with another therapist to discuss the first therapist to see if what she did was ok or not. In either case though, you don't have to stay with a therapist who is making you feel worse rather than better.
