Welcome to the forum, Thrace. Don't worry, this is new to many of us. I for one haven't been diagnosed at all and when I joined this forum I felt like a complete idiot, sometimes still do.

But people here have been very understanding and helpful, and there is loads of good and valid information on DID, links and tests.
I'm not sure if I even have DID, perhaps DDNOS is more likely in my case. I'm hoping to find out eventually, with the help of professionals. Nevertheless, this is a good place to be in the meantime.
