A therapist that makes you feel unsafe and gives your mom a platform to defend the person who molested you probably shouldn’t be allowed to work as a therapist. I would find a new one…

Also forcing you into an uncomfortable physical situation with one of your abusers while you literally are going to therapy for trauma resulting from sexual abuse seems like the therapist is further inflicting trauma on you. Frankly this whole session sounds terrible and I’d report them before I’d ever go back.
