I've been reading a book about DID. It is First Person Plural
, By Cameron West. The title of the book isn't catchy, but the book is very interesting and very helpful. He was a victim of mother abuse (incest) at an early age. He describes the multiple personalities and how they appear. He describes how the condition appeared and how it affected his job, his wife, his young son, and everything else.
I haven't quite finished this book, but I know enough about it to recommend it highly. One of the things that we survivors who have DID or DIDNOS can use to help ourselves is to read books such as this.
This is an important book on DID.http://www.amazon.com/First-Person-Plural-Life-Multiple/dp/B000FDFWN2/
