I used to have work friends who knew me one way, and family who know me on way, and long time friends who know me in another way. I would never have them in the same place at the same time. It only happened once or twice and it was torture for us. I didn't know than we were a system. I never knew why I never wanted to have my friends from one part of my life meet friends from my other part of my life. It's like worlds colliding. No one knows we are DID. I have told my sister and son I have PTSD and sometimes dissociate. It explains my forgetfulness and anxiety issues. I have three parts who lived and worked in the world. They made the friendships. We all liked the friends they chose. And if we didn't, if someone triggered one of us, we'd drop the friend. Now we don't try to make new friends. We are social when we need to be but that is it. It's too much work. But we still have our long time friends and siblings.
