So. I have a fractious and somewhat controversial disorder. I have two mental disorders actually, but one is far less fractious and controversial (until you look at treatment methods and then phew! The controversy comes back). I have post-traumatic stress disorder, and dissociative identity disorder. I could hide those diagnoses from everyone because…that’s what people do. They hide this stuff. They hide it from loved ones and employers and clients and even medical professionals (I know I do, sometimes, because dealing with the stigma from medical professionals is its own kind of special pain).
