starting to hate my family

30+ weeks pregnant.
My sister told me a few months ago she was moving to the other side of the country next summer, I was upset because she won't really see baby and she lived about a half hour away from me but understood.
Then me and partner split and I moved back into my mums around the corner from sisters, sinse I've come back, my mum who has never bothered being motherly is constantly checking to see where I am because she doesn't like ex and wants me living in her home so the baby will live in her home.
My sisters like oh come stay in mine for a break, came to stay and she had her friend here at 7am shouting away, it's now 1.30 am and she's decided to go on a tidying spree banging around everywhere and moving furniture. I'm literally crying with tiredness.
I mentioned wanting to try make things work with baby's dad, they don't want me to because they don't want to have to travel to see the baby, my sister had actually tried blackmailing me saying that she won't move away as long as I stay living here so she can see the baby every day.
I just can't cope with them, they're making me feel completely pressured into something I don't want for their convenience and don't care about things like the fact I'm 3rd trimester, sore and exhausted. I don't know what to do, I'm so tired and sat here sobbing 😭
