I've never really been that interested in having friends. That's probably worth an analysis, but we'll leave that for another day.

I mention it though because I think it's germane to how I haven't had nearly as much difficulty in getting along with what you've described as 'normals'.
I have DID. I make no apologies for it. I don't tense up or get embarrassed when I explain it to someone. I don't use the fact that I have DID to make excuses. When I share my dx with people, I explain it as if I was explaining that I have brown hair. I really don't care what anyone thinks about it - fact is, if they had my childhood, they'd have DID too - if they survived.
So, I go to work...unless Sonseearae shows up, in which case she works. I'm in management and so I have a staff that works directly for us - they'll greet whoever shows up and they take direction from whichever one of us shows up. I'll stop off at the local Walmart on the way home to pick up prescriptions or the days groceries. The cashiers and pharmacy staff have met both of us (there are more but they don't make public appearances often) and treat us equally. Our local Starbucks knows who is who by the drink we order and puts the corresponding name on the tag. In fact, the employees get recognition for knowing 100 customers by name and their regular order and the last employee to receive that recognition did so by fulfilling customer number 99 and 100 with us.
I assume making friends would be easy using the same 'no apologies' kind of attitude. We are friendly, we don't make a big deal out of it, and no one else does either.
