great letter, thanks for sharing...

what helped me when I was going through denial\questioning my diagnosis was two things...

my treatment providers went through the test results with me and took it one step at a time explaining to me how those results fit me.

my treatment providers told me that getting the diagnosis doesnt change anything other than puts a name to what has already been happening all my life. did I question the fact that I lost track of things before my diagnosis...no ...why because it was my normal, thats how I always was, did I question the fact that I heard voices sometimes before I was diagnosed no, why because that was my normal did i question the fact that I knew in some way that Rainy was there, no, why because that was my normal.... everything that is DID was how I was since before age 5 due to extreme trauma. a doctor saying hey you have DID didnt change all this, it just put a name to what already was.

what was hard for me was when the alters integrated\became one with me because that wasnt my normal.

As for "accepting" the others were me, that never entered my therapy process, simply because each of my alters had their own way of being, their own jobs, purposes, reasons for being created( in other words their own sense of agency) as a result of having this kind of internal system they did their own thing and I did mine, and when their jobs, purposes, reasons for being created (their sense of agency) was no longer needed they just merged together back with me to be one whole person again.

suggestion maybe sit down with your treatment provider and go over the test results so that your treatment provider can show you how and why you were diagnosed with DID, then if you still have a problem with this you can ask your treatment provider for a referral for diagnostic testing. this way if you are not DID the updated evaluation will tell you what your present diagnosis is and why.
