Same here. Socializing is a huge energy drain, and just knowing how badly it's going to drain me is often enough to send me into a mood episode if there's a big event coming that I can't get out of. "Luckily" I have schizoid features next to my BD, so I don't feel a need for friends and I don't really get lonely. The pressure to socialize comes mostly from work-related events. I used to think my dislike for socializing was due to the schizoid features, but now this thread has me wondering whether it might have something to do with the BD as well, even though I don't yet understand the mechanics of how that would work.
