I have only recently come to the idea of DID. I just have a couple of things that strike me.
One is that I know how scared I was when I first started to think in ways which seemed to me, "odd" (no offence meant!) What helped me was the people here who accepted me as I was, as I appeared to them, and didn't try to make any assumptions, or judgements, or tell me what I was "really" experiencing.
The second is that from what I can see we all have slightly different experiences of any kind of mental illnees, because we are all different. It seems to me that, by and large, this site celebrates and encompasses those differences, rather than trying to put everyone into boxes according to their diagnoses. The thing I have really noticed about this place is the kindness and humanity of people rather than the concern about being right. And, again in my experience, kindness and humanity are often much more helpful than the textbook answers.
Just my thoughts.
