I don't know. I had one counselor that said its not necessary that I remember EVERYTHING and I had a counselor that said for complete integration where I never again have to worry about switching, forgetting things all that junk that comes with having MPD or is it DID? anyway Ive been told both ways so Im just going to throw out worrying about it and just let things happen as they will letting the memories come when ever my head thinks its time to give me another one.
