I think one reason that people don't want to believe in DID is because there is such a stigma to it. It is terrifying in so many ways when you realize that you are not in control all the time.
There are only 3 others who know about me (including my T). I wish the only person who knew was my T. I lost my bf because of it and because he knows. I warned a potential bf about it and he dumped me the next day. I am very sad that he knows. I'm not telling my family, workmates, or neighbors. They don't need the burden. They don't have to come to terms with it. And I'm not going the bf route any more. That makes me sad too.
I don't want to have to explain myself to anyone. I don't want to have to justify it or explain it. It isn't their business. It is difficult enough all ready.
