Just need someone to listen 😔

So last night my mother got really drunk and it really upset me , i just moved back home because i was having problems where me and my fiancé were staying and i just found out at the beginning of the month that i was pregnant my mom had been back drinking now for maybe a year or less after being sober and it really bothers me because she won’t even eat sometimes i try to talk to her she says she will stops but never does I’m pregnant i would love to enjoy my mom and how she use to be but seems like that won’t happen... i got really angry and punched the wall i hurt my hand and i feel like shit because i allowed myself to get really mad and didn’t think about my child that i am carrying
