I'm not so sure you can divide them up... as those with Dissociative Identity Disorder have it as a coping mechanism due to an overwhelming stress event (thus the PTSD.) Trying to figure out which is which, or even considering them separately seems futile, imo. It's close to going back to the mind or body issue... both! DID is what got you through the event, PTSD is what happened to you because of the event? ((hugs))) sorry you are dealing with all those symptoms!
