"Friends"

It seems like since I've gotten pregnant..EVERYONE has disappeared. I get it, we're all adults and living our own lives. But one hasn't talked to me since my first ultrasound because she begged to come with, I let her. Haven't heard from her since. The other had people over and didn't invite me, I know I can't drink but I can still hang out. She claims it's because "there's people there I don't like" okay and? You've talked shit about those people and you've got them over? Makes sense. I just feel so left out of everything. I had my first born at an early age and I lost all of my friends during that pregnancy and it feels like that all over again. I don't understand why people can't just be happy for me and be there for me. I'm there for them through literally everything. Complaining about boyfriends/husbands, babysat their kids when needed, took them out when they've had a bad day. I'm SO tired of being there for everyone when they can't be here for me. Friendships work both ways. It's getting to the point that I want to delete my Facebook because I'm so sick of seeing all of them tagging each other in best friend pictures and not me. Why not me? It's upsetting and maybe my hormones but I don't see it as very nice.
