Hi,
Most of us have been there; false diagnosis before the dissociation is recognized by T's. I think this is a complex subject. Most 'false' diagnosis multiples get, are also trauma related or, should I say; induced when genetically 'present' already, by early childhood trauma; the whole cluster b category.
What makes it extra difficult for me personally, is that my mother used to project her cluster b traits on me a lot and send me to shrinks, to a degree where a T I had, ten years ago, labeled hér with munchhausen by proxy. That same T was the only one who did several tests on me over the course of a few months I think. She ruled out almost all in my subscription, and diagnosed me with the depersonalization, (also) ptsd and maybe a personality disorder not otherwise described, because I didn't show all/'enough' symptoms of specific ones. She also brought up DID, but never officially.
It was traumatic for me that I was psychologically abused with 'accusations of disorders' when I was an innocent child who was being abused in many ways by the same person who accused me, but I've been processing that. I can finally keep things apart more, am less scared of getting labled (always had the feeling that would mean that she was right all along and that this would mean that the abuse itself was my fault), and now I'm at this point where I wonder; how to 'decode' this thing!
For example; I get how BPD resembles DID a lot, but I keep wondering; isn't it actually the same disorder, with éxtra dissociation in case of DID? Bad emotion regulation by different parts, is the same as bad emotion regulation by a whole person? The only difference is, how should I put this; the more severe interrupted awareness in case of DID? And when can one tell if a system is a 'black and white thinker' because of a personality disorder, or when a system had to rule out grey arias during childhood (victim/abuser) for protection? How does it acutally matter, the difference, in treatment?
How does it matter which traits are internalised and which ones were already there? Treatment takes longer when they were already there? How to tell the difference? When certain traits exist only in a few parts, for example?
How on earth do professionals come to proper diagnosis?:)
