Fed up with my own mother?

I am a very southern raised girl although my family lives near Chicago. And I was taught to respect your elders, and love your family but I am trying so hard and getting fed up. Let’s start here. 03/2017 I found out I was pregnant with my son Eli, he wasn’t planned but we loved him just as much and my mother would constantly flip out and start yelling over anything and everything. The day we had the blood test to confirm I got told I killed the dog because SHE bought a rawhide that got stuck and he needed surgery, so I couldn’t even bring my myself to tell her. After her and my stepdad screamed at me and we’re gonna kick me out because I model and had done a pin up shoot months prior that she didn’t like although I’m 20 years old and the most scandalous thing was a panty line, they had me to the point I was pulling my own hair out and hysterical trying to leave my room for my very large stepfather to push me back in. Then throughout the pregnancy he didn’t “approve” but it isn’t for him to approve, it’s my body. So I was working a job where I constantly was harassed and get a new job but get yelled at for quitting my old one even though I was working fifteen hours a day. So I start waitressing, after a few months I hit the six month mark and explained my body couldn’t take it I was exhausted, but she screamed at me and screamed at me about money so I didn’t quit at that time to avoid the extra stress on the baby. So I’m at work and get cramping, she refuses to drive me to the hospital and makes me wait for a doctors appointment. So I go to this appointment at will county medical health facility in Joliet and as the nurse asked any concerns for the doctor I explained I had some major cramping at work, to which she responds “I can’t put you in disability” then I argued with her because I just wanted my baby to alright, don’t care about money. So after that, the doctor walks in and I tell him and he goes to take the heartbeat and freaks out, doesn’t say a thing but I’ll be right back and wheels in an ultra sound machine, from new the heartbeat and says everything’s fine you can work but take it easy and has me leave. To which I call my mother because I’m convinced I need to see someone else which she tells me imjust freaking out. So I quit my job and her and my step dad complain I don’t do enough in the house. Needless to say helping them one day I started gushing blood. I had had a full placental abruption and lost my son and had almost died. Withou blood transfusions i wouldn’t be here typing this. So my fiancé is by my side the whole time through this. We get home and his mother who was supposed to help us with the urn cost because he was out of work while I was in the hospital started being insane so my mom was gonna help us out and then her and my stepfather got into because he makes over 80,000 a year and can’t stop buying farm equipment we don’t need and flipped out.. all as I’m having a mental breakdown from loosing my son... this was in October. It’s not February everything I do is wrong, she pushed me on birth control before I even got a full cycle so I had some weird spotting and my gyn said take a test because I was taken off the same birth control for excessive bleeding just to rule out pregnancy, I get screamed at for that?! All I do is try to appease her and clean and be nice but everything I do is wrong. I got yelled at for apologizing for having three pairs of shoes at the front door because “I shouldn’t apologize I should just do what the f*** she ask”. Her and my stepfather act like they lost their child and I went through nothing. Everytime I talk or speak my opinion I’m being a bitch apparently... we were fixing our car so we paid her to give my fiancé a ride to work and she said we’d leave at 8:30, at 8:15 I start coffee to take with and she starts yelling because I’m going with and I apologize and say if it’s an issue I can stay home, then she starts going on about the coffee and I say I can leave it, also not a biggie. And she gets mad says I have an additive and smacks me so hard in the back of the head my fiancé heard it across the house. I need to get out but we don’t make enough money. She’s my mother and I love her but why doesn’t she seem to have to same love back. I lost my baby and get yelled at for having depression. She tries to tell me how my body works and I just keep holding resentment because even though the doctors said cause unknown I just know it’s because of the work and stress... I need advice or some words of kindness...anything. “I’m so far gone now I’ve been running on empty”
