Family First?

So like 30mins ago I'm talking to my mom and she snaps on me..saying she is sick of me...🤔 I'm here visiting and she says that shit to me. I've never disrespected her..I just graduated from medical school. I never was a trouble maker when I was younger...I literally busted out crying because has never been the "nourishing " mom. But lately she's been so hateful. I even planned a special announcement for my pregnancy for her bday next weekend... Idk if my hormones have gotten to me but damn..😢😢 I just want her to be happy and say she's proud of me. My SO said not to let it get to me because I have to chance now to love my baby how my mom didn't... she's even mean towards my lil brother who is 4. Yes he's bad but she doesn't show him love or take him out the house..she just yells all damn day.. 😒
