Yeah I kind of don't have friends anymore. I got unexpectedly pregnant for the first (and only) time four years ago and my friends slowly dried up after that. I haven't heard from my best friend in about a year and a half. It's tempting to think that it's my fault, since I have PTSD and have trouble maintaining connections to people, but really I think that my friends weren't very good people.
I think it's easier for me to be friends with self-centered people because I don't feel like they are prying into my personal business. So naturally, those people are not going to be there for me long term.
When I "came out" to some of them about one of the major things that happened to me that gave me PTSD they were like, that sucks, but I could tell they weren't really thinking about it and then they were like, back to me. But it was a relief. I didn't want to talk to them about it. I preferred to hear about their drunk shenanigans and poor life choices.
