3 more days of this garbage

I’m currently living with my step mom but I’m moving out this Saturday thankfully!! To a whole other state. Her and my dad are in the middle of separating right now and he pays for the house my step mom just pays for utilities. But he doesn’t live here. I’m just sick of paying her $600 a month to live in a god damn bedroom, she hasn’t bought groceries in month except to meal prep for herself so my half siblings are eating off of what I buy. Which is whatever but I don’t have a ton of money and it is SO stressful to have the stuff I buy go that fast and she never helps out or replaces anything. And they’re my siblings so I’ll never ever make them feel bad for it because they deserve to eat and I have no problem feeding them, I just have a problem with her not ever buying food for the house. She also expects the house spotless when she gets home from work every day. But why am I expected to be a maid, buy food for the house and pay her $600 on top of that?! Plus we help her when the water bill is too high. My siblings haven’t done their chores since we came here and she yells at US when they’re not done. I’m fucking 23. I can’t wait to be in my own place on Saturday. Also, I really hope she buys the kids groceries once we leave. They live off of ramen and rice with bbq sauce and cereal most of the time when I can’t afford to buy food for the house. Thank god this will all be over on Saturday because I’m sick of hating myself over the things she says.
