I guess I don't equate recovery to being integrated. I think those with DID need not completely integrate to be happy, functional, etc.

If I got too much negativity from my T, I would seek out other sources.

I have a book I like about women with DID who lead successful and fulfilling lives, unintegrated. Maybe this book would offer some hope or inspiration for you. This is the book:
I Am More Than One -- How Women with Dissociative Identity Disorder Have Found Success in Life and Work

Maybe you and your T could read this book together and have "book club."
