What clued me into the fact that I am DID:
Just as an example, I have extreme behaviors - almost like two different people or three actually. I can be very upright and try to do things very properly. And I can can be very self-destructive. Or i can be a 'high- class" type person.
For me when the therapist told me the diagnosis - it came as no surprise - it fit me perfectly. When I then sat down with pen and paper I was very easily able to draw a diagram of myself showing my different parts or "personalities" . Of course I am only one person,but I operate as though I have different agendas depending upon who is running the show at the moment.
