FTM overwhelmed and venting

Today is the first time that I've actually freaked that I'm going to be a mom, my niece was up and started crying hysterically for her dad and everything i tried to do wouldn't calm her and this went on for a half an hour till her dad came home, I'm now sitting here on the verge of tears panicking that im not going to be able when my baby comes. I'm also back home with my mom and her husband while me and other half save for a house as rent is too much and all her husband does is drink constantly and smoke then hides it all before my mother comes home and catches him and theres no talking to him so now I'm also freaking that we'll still be here when baby comes. theres no point to this post I just needed to get this out somewhere and vent 😥
