I've hit rock bottom

My best friend from high school called today. She got married and called to tell me she's pregnant. Jaw dropping for me. I am happy for her but then I had a sudden realization. Everyone around me is dating someone, involved, engaged, married or having kids. I think I must be the only single girl left!! I feel like such a loser and then, frustrated, I called my other friend hoping she would make me feel better about being fabulous and single. Well how can you meet someone? You're married to you fucking job and work with nothing but gay or married people. HELLO.....now's the time you comfort me and say screw that. UGH....I know I am not the only single person out there but damn, I am starting to have a meltdown. Am I being too picky, independent, stupid...WHAT THE HELL AM I DOING WRONG? That mid 20s crisis thing must be kicking in early.
