how to deal

i don’t want this to come off selfish at all because i’m so happy for my friend but she just announced her pregnancy with her boyfriend and i just broke down crying. we’re both in our 20’s (her early 20’s my mid 20’s) and it feels like it’s happening to everyone around me but me. it feels like it’ll never happen and i haven’t broken down like this over a baby in a while so it’s hitting really hard right now. like i said, im so happy for her and i would never try to bring anyone down for having a bundle of joy in their lives! please give me advice on how to deal 😭 (it’s not her. it’s just in general)
