Advice: A T needs to make your getting well the core focus and their opinions on diagnostic minutia a secondary concern, right?
You really need to share with both of them that this discrepancy is causing you to feel stuck and stressed.
--On a personal side note--
As a kid I related to the "Velveteen Rabbit" who constantly asked the question "Am I real?" This existential question reverbs for me with my dissociation and my amnesia for large parts of my early childhood. As long as I can remember, I was aware that I was "not real."
My discovery behind this sense of confusion is that I have been lied to all my life about everything important to my sense of identity. Lies upon lies from both parents who told me they knew the realities and was dependent upon them for the truth. Rather the opposite is true. They have done nothing but pretend and lie, and I have always had the truth but didn't know it WAS the truth because it lies in stark contrast to the gaslighting.
The question became "how do I still retain this sense of "I" as a constant after all I've been through.
I honestly see DID as a collection of states growing up gaslit constantly where the rules changed. A set of separate identities were the side of effect of the shifting roles that were demanded by that kind of situation, nothing more.
For me, I see a lot of identity as performative anyway. Even when I'm alone, if I try to feel or think outside of what I'm showing myself that I'm doing, I cannot. I cannot find a way to be authentic and not somehow "acting" even when I'm alone.
I believe that my dangerous environment shifted my sense of self into survival mode in which I have always to be predicting and responding with some kind of dance to my environment. So much so that I have developed severe phobic reactions to non-trauma related things, such as crowds because I try to read the 360 degree of the crowds by default and cannot switch this off. Yes, this is PTSD, but where DID comes into it is how there is no luxury of a return to rest within an authentic self at any point. I see it as having PTSD from too young an age to have developed what others refer to as a self. I have states that I work within, like masks, and underneath the mask is always more masks. Where is my face? I cannot find it. I have no memory of such a thing as a core self within which to rest.
I have called this "my missing baby" and I began searching frantically for this in my dreams back in 2010. :(
