I have an alternate personality. Not like a medical disability (though it could be argued that the paranoia that started this is a problem), but like a fake life story I use when I need to participate somehow but don't want to use real-life details.
This started from online gaming when I was in highschool for safety reasons. I chose a fake name, and built a life story for myself. As time went on, it got more elaborate and I started using it IRL as well in situations where I didn't want to talk about myself, but there was some sort of social obligation.
It's become a habit at the point to just use my alternate name if I'm not required to use my real name (like for legal reasons). Like small talk with a person I'll never see again at a bar or something. This means, socially, I'm effectively two different people that are never in the same room.
The problem here comes from the fact that I've been hanging out with a group I originally introduced myself to with my fake identity. I'd like to move them over to my real life, but I have no idea how to even communicate that everything they think they know about me is false.
The fake identity is not intended to hold up to scrutiny, it is literally a means of getting out of answering questions I don't want to answer. So this is generating a fair amount of stress. I didn't anticipate wanting to make this activity a larger part of my life (swing dancing) or interact with these people outside of the activity itself.
So how can I explain this to these people without losing their friendships?
