I need to vent!

I feel so freaking alone in this pregnancy and my husband treats me like garbage, he drinks beer every single day as soon as he’s home from work until he passes out drunk and just plays on his phone all day, then complains because I don’t have sex with him. We have a 5 year old(not mine biologically) a 1 and a half year old and I’m 32weeks and 4 days pregnant with a very high risk pregnancy, I do everything, he does help but also complains a lot when he has to actually do anything. I have absolutely nothing prepared for this baby because I cannot get help to do anything at all, between my job, school for the oldest, doctors and specialist appointments for not only me but also the 1 year old because she has breath holding spells, i just don’t have any time to do anything other than pick up the house so it doesn’t look like a freaking tornado hit. Today I had to go to labor and delivery because they thought my amniotic fluid was leaking (Thank god it’s not) and I was told more than likely due to baby’s position I will be having a C-Section and I’m freaking terrified but of course he comes and picks me up from the hospital and as soon as we get to his family’s house, he starts drinking, when we were on our way home he started being really disrespectful to me and calling me all kinds of names and telling me I’m a loser and my whole family is full of losers and that he has a piece of shit wife and y’all I made one comment JOKINGLY at his family’s house and “I started it”. While I was at the hospital he was saying he was gonna rub my feet and take care of me tonight and of course whenever he says that he has to start some kind of argument and or disagreement so he can get out of it. Now he’s passed out on the couch and won’t even sleep in bed with me because I’m a loser according to him. And he’s always saying that the reason I’m still around is because he has to keep me pregnant so I don’t go out and be a whore anymore ( I am not proud of my past, but I married this man because I am not the person I was before I met him and his son who I have been raising for 3 years) I’m just really at a loss and feel so freaking alone and miserable and knowing I’m gonna have to have a c- section scares me so much because I’m not gonna have the help I truly need, I don’t know what to do anymore.😭
