I remember staying up all night reading the book back in the 1970's. I didn't care for the movie. Don't know if "Sybil" was real or not. I know the movie had a lot mistakes in it. This movie and a lot of other media crap did not help in understanding DID. Maybe no one ever really will.
I just know having DID helped me survive.
Has anyone read "When Rabbit Screams"?
