I feel exactly like you.
If I loose my whole mental disorders "tag," then who I am? I'm no longer the borderline, identity-dissociated guy who harms himself and looses track of time.
Who am I? That's a very deep question. I'm sure a mental disorder is not enough to answer it.
I do believe that you define your own identity. Even in my case - "I" have multiple identities/personalities, I believe that I'm who I am just "because," not because of any mental disorder.
Obviously I'm a very empty person because most of my feelings "belong" to my EPs (Emotional Parts) and the control of "myself" is usually done by the ANPs (Apparently Normal Parts).
Integration is supposed to be the first symptom of DID healing. I'm afraid of integration. I sometimes feel lucky because I don't "have" to be angry, sad, stressed... But of course, I'd love to be "awake" and don't have to dissociate when one of those repressed feelings has to be felt.
I know this is not the DID forums and it doesn't belong here, but that's how I feel and, all in all, I do believe that DID is just a form of C-PTSD.
I'm afraid of getting better. Sometimes a happy life sounds boring to me.
