Irrational rage

There's a bit of history to this and various reasons why I'm so upset. But basically... Every time I'm having a baby (twice now) another in-law gets pregnant. Not because it's their time for wanting a baby, but very obviously (as in discussed Infront of us and online) "oh they're having a baby I want one too!" .

I feel like a petty, evil, irrational fool for being angry. But I am. Both pregnancies started with hyperemesis and I've not enjoyed them. But I love my kid (soon to be kids) and it makes me sad that the most cherished part- finally welcoming a child and waving adiós to pregnancy has kinda been overshadowed by a pregnancy announcement. First time I was 28 weeks this time I'm 33. I'm in for the exact same I had last time... "Oh can you believe we'll have one of these soon" Nevermind the bloody birthdays "oh it's yours first birthday then ours so soon after!" I'm not even gonna have a kid start school by themselves. I'm quite emotional and don't wanna share it. let alone twice. I am lucky for my husband. For my son. For my new baby. I need to breath and let this go but I also need to... I don't know? How do you get over things that don't really matter but still weigh heavy in your chest 🤷
