With trauma, before repair can take place (psychoeducation or "giving it a chance to have a different outcome" as your t puts it) there has to be a relational connection one-to-one in an emotionally neutral space. Before that emotionally neutral connection can be present in the room there has to be two regulated selves. That means neither of you can be emotionally triggered. It is neurologically impossible to learn a different outcome in a state of trauma arousal. Regulation must come first. then connection. And only then will she be able to show you what she wants you to see.
In that triggered state, through no fault of anything but human physiology, she is asking you to do the impossible.
This isn't a criticism of your T. She truly wants to help you. She is doing the best that she can, trying as hard as she can try. She just doesn't know what she doesn't know.
