@AriesAriel I don't know what you have, you ought to see a psychiatrist to get a definite diagnosis. It's difficult to say what it might be, for example, it could be some kind of schizophrenia thing, or a dissociative thing, or then again, it could be a narcissism or borderline thing. It's hard to tell on so little information. It would be easy to jump to some conclusion of dissociation, but like you said, you don't have a childhood history of trauma, so it shouldn't be that, unless you don't recall it. An adult forming the disorder doesn't occur, so if it started 17 years ago, I don't know, it doesn't fit. Really hope you find someone who can help you.
