I don't feel unrealistically threatened. I, like you, am complex, and actually I have complex PTSD. Since I don't have DID I can't advise you on that. Have you thought about cross posting to the DID forum? I don't see my tendency towards narcissism as a separate part of me. The internalized critical voices of my family, ex, and some friends are not me, but they are in me. That is what I want to expunge or silence. The way others have spoken to me has not been good. Now as an adult I can stay clear of those who hurt me.
