Family problems

Hey girls , so I’m 19 (almost 20) I’m still living at home with my 2 and a half year old I’m currently 19 weeks pregnant and my sister and I had a petty fight (like twin sister do) about wearing eachothers clothes when I was looking for it ect... so my mum (like she always has done) sticks up for my sister. Now she’s so fucking mad, I said sorry to her and the day after she messaged me the meanest message saying “I’m blocking you good luck with the new baby your gonna need it with NO ONE TO HELP I would adopt it out if I were you to give it a better chance at life” that upset me so much and last year I got an abortion and she said something mean as fuck aswell to me. I can’t look at her the same yet she’s still angry with me, my sister and I are talking normally and fine? She’s not coming to my gender reveal because she’s “said too much” and she didn’t want to come. I feel like she doesn’t care about me and she just always sticks up for my sister and makes me feel like I’m being attacked my everyone being against me. She reckons she’s moving out in a few weeks, which my dad probably won’t agree with? Wtf. Can I please have advice :(
