Welcome to PC Airfobrat. You can share your story at Psych Central, but I am not an expert on DID so telling me might not get you more than a good venting.
My first impression is you might want to seek out a psychiatrist to see if medication could help stabilize the situation.
A therapist also could be a help.
Not letting people know as you revealed here is a smart move. People tend to put people in categories when they don't understand.
When you say insiders, would you describe them as voices?
Since you don't have a lot of people to turn to, it seems necessary to seek out professional help that can guide you through the situation.
It is Friday night and so maybe over the weekend you might get another post from someone here at PC.
