I’m reading about DBT now, which focuses on learning to be non judgmental instead of negative. It may help you. I just started it. In theory, if I can do it, it has to work.
Something happened this morning that triggered trauma memories (It was from the person who caused the trauma and regarding an issue pertaining to the traumatic subject). I got upset, but thought about the DBT ‘radical acceptance’ idea. I calmed down and then could think about what I can do to make the best outcome, which I did, and all was okay. I hope the relationship improved slightly as a result. It certainly didn’t deteriorate more, which it could have, had I reacted negatively.
