Not really.I don't know of any mental health provider that is going to immediately start treating someone for a self diagnosed disorder without confirming it first themselves.

Maybe that's where you have been going wrong,by telling them what you have and expecting to be treated for it?

Maybe it would be better if you allowed them to do the diagnosing?I know I said it before,but I feel if you have a dissociative disorder a professional will recognize it eventually,maybe not in a time frame you would like,but eventually they would.
