If you were diagnosed with - just say X - but you knew it wasn't, but everyone said it was, so you were stuck with it.

If a few years later, the regular Dr wasn't available, so you saw a different one and the one time he saw you - you got diagnosed with a personality disorder.

But your new Dr didn't understand why and wanted to go back to X - but is doing a new assessment anyway, would you still have the personality disorder?
