I explain the 5 different types of DID to people that I trust to tell them my diagnosis only my husband, bestfriend and one of my sister in laws know and they accepted it pretty well.
Mother overheard my husband and I talking about it and had an anuersym she didn't understand DID until I said used to be known as MPD, then she was in denial for a while.
The thing is I believe there a various states of each its not uniform at all.
MPD is the most common one due to media its new name DID is less common and the other 4 dissociative disorders not many people have heard of before.
It's hard for me to explain it too and I guess if I had DDNOS it would be harder and I do understand what you are saying my friend.
