MY MOM

ok so I love my mom. I really do. but I'm 30 and we still live together. I say live together because I pay for more than half of everything. I work 6 days in a row and she barely works one. I have2 girls whom she babysits. but her idea is babysitting is being home with them. she goes into her room and shuts the door. so my kids just destroy stuff. recently we went out to dinner for my daughters bday and she had no money to eat. so I spent my last on her to eat. and I didn't eat. but I made sure her and my kids ate. my aunty had told us( me and my mom) she would give us money to help with Xmas so At the end of dinner she gave me and not my mom the money and my mom was LIVID! all because my aunty gave me the money. and not her. so she's been walking asking slamming doors just mad. then tonight she tried to pick a fight because she thought I took her charger. but we have different chargers. hers don't even fit my phone. I bust my arse to take care of her and my kids and this is the thanks I get. my ex always told me she was dragging me down and I need to move on but I feel guilty. I feel like she not gonna be ok if I leave. I love my mom but she is stressing me out so much. I don't know what to do anymore.

UPDATE!!!!

so since she doesnt have a car she's been using mine. well last night she parked in the wrong spot and got my car towed! and I dont have enough to get ir out. at least nor until Friday and she has NO money. I told her what happened and shes just laying in bed sleep. not tryna borrow the money or anything. so basicaly I'm calling everyone I know tryna borrow the money. but here's the bad thing. the money I'm borrowing ima have to pay back out of the girls xmas present money. so now they will probably not get anything for xmas!
