What a horrible experience to have with a therapist! Not all trauma therapists are equal I guess....she doesn’t sound prepared for the job she chose at all. Or maybe she was struggling with her own issues and realised she couldn’t help you for whatever reason, felt guilty and pulled away? That’s no excuse for her to make you feel you don’t matter though. I hope the next person you see is really there for you and makes you feel seen and heard, because you are important and your life matters!
