Of course there's hope.
Maybe there is no "cure" but think about what you've trying to cure. It's a coping system.
There is treatment. You learn to deal with it.
I've seen more results from therapy since i was diagnosed DID last june, than in the six years before. If I could have told my therapist about some things eariler, it would have saved me a lot of misery.
sorry your feeling so down, but things do get better.
