Not having family in my life anymore? Need help please!!

This is going to be a long post, but I really need help. I am 9 weeks pregnant with my first child and I am seriously debating on whether or not I want my family in my life anymore.

A little background, my life was tough growing up. When I was 9 I got into a car accident where I flew threw a windshield and hit a tree and my little sister died. My mom got into drugs, blamed me for my little sister dying and said some very awful things to me which ruined any chance of us having a normal relationship. Me and my twin sister had to go live with our grandmother. She beat us nearly every day and verbally abused us constantly. It was horrible and we were both glad to get out of there. Once away at college I didn't talk to my grandmother as much. I wanted to completely stop talking to her but she made me feel guilty so I continued. When I met my now husband, he made me see that she was only making me unhappy and that if I didn't want to completely cut her out of my life then I could slow down on talking to her, so I started only talking to her once every couple of weeks to update her on what was going on. In 2018, me and my husband were in a very unfortunate situation where we were homeless. When my grandma called, I told her what was going on and she said we could stay there until we got on our feet again. I didn't really want to, but we had no choice. We stayed there a month and 3 days. It was absolute hell. She threatened to kick us out every single day, was demanding we pay her $1,000 when we did finally get back on our feet and to make matters worse my aunt (who has been to prison for drugs and is STILL on drugs to this day) was there and of course she was angry all the time because that's what the drugs did to her. It was an extremely stressful month and we got out of there as soon as we could. We paid my grandmother $350 for the month and three days we stayed there. I didn't talk to my grandmother until Christmas eve to tell her I was pregnant - an ENTIRE year later. I didn't really want to tell my grandmother but my sister convinced me that she deserved to know.

Well a week after I told her I was pregnant - and even went to see her on Christmas day - we got kicked out of our house we had been staying in. The owner of the house said she wanted to move back in because she couldn't afford her retirement community anymore. She only gave us 2 days to move. I'm aware that this situation isn't legal but she gave us back our full deposit and last months rent so we decided not to get lawyers involved. It just happened that my grandma called and asked how I was doing a few hours after it happened. I told her we were trying to find a new place to stay and explained what had happened. She said we could stay there until we found something and mentioned nothing about payment. We were there for 5 days before finding a new house. It was okay, until the day we were leaving she said she wanted $350 like last time. She also told my aunt I was talking crap about her and had all these text messages on her phone as "proof" that I was talking shit (the number was not my phone number), and once my aunt started crying to me about it my grandmother dropped it. She's so much drama. We told her we weren't giving her that much money for 5 days because at that point we could have stayed in a hotel. But we told her we would give her $100, because it was only five days and we did buy food for the house so us offering that is generous. She said no, that she needed the $350 because she couldn't pay her taxes on her house. A side note about that - she spent $4,000 on a boat that her and her sisters use not too long ago. She's nearly 70 years old and still doesn't know how to handle her money. She's blaming me for her not being able to afford her taxes and is texting my phone threatening to show up to my house and not leave until she gets her $350.

It's just too stressful. The year that I didn't talk to her, my mom, or my aunt was the happiest year of my life. I wasn't stressed out at all and me and my husband were actually able to conceive this time on the first try (we had tried previously for a year but nothing happened so we took a break).

I have already blocked my grandma and my mom (because she's also blaming me for some reason). I'm seriously considering just leaving them blocked and not having my baby in their lives at all. I'm just so tired of being stressed out over them. They make me feel guilty for not having them in my lives. They just don't understand how destructive they are - well my grandmother does but she doesn't care. I did plan on keeping them updated throughout the pregnancy but now I don't know. Do y'all think it's the right choice to not have them in my life?
