Whatever you do just don’t get tested for it. If you want treatment align it with C-PTSD. There are minor differences so it isn’t hard. Treatments have the same effect but having that diagnosis on your official chart make finding a doctor to help you extremely hard. Your mental state will always be in question even if it’s for something like back pain. I have it, officially undiagnosed but that was from the advisement of my doctors because they know how BPD is handled in regular medical care.
