Rant about family

So I just had my first ultrasound my fourth baby announced it to my sisters and all I got was a ok & I already knew.I can't help but to feel a little down these are my sisters ones I was excited to tell immediately I would if thought they'd be happy I just got left on read idk if it's the hormones but I'm in tears for other people they'd be so hehe haha with congratulating them an what not they don't even help with anything I've never bothered them to care for my children nor buy them things. 😥 Am I overreacting
