And here lies the problem with online therapy. Things can be said that people wouldn't dare say to each other face to face. What your therapist said is completely unacceptable and had nothing to do with you or your behaviour and everything to do with her crap boundaries and her inability to recognise when she's getting burnt out. She might have 20 years experience but it goes for nothing if she can't pace herself and by the sounds of it she can't pace you either. You may have ptsd but what is her qualification for dealing with that?
What she said to you is unprofessional and damaging. Go find a therapist that you can meet face to face and one who can actually help you.
