Family pressure

Right now I'm living with my parents they have a large house everything was okay recently a relative moved in and she told my parents that adult children shouldn't live with parents and she doesn't pay rent, she doesn't clean or do anything and before she came I would clean the house and I stopped when she arrived my parents and the woman living here can clean up after themselves not my problem anymore.

Today they were commenting about me she doesn't clean up and I felt so angry there's this woman living here she has the whole basement to herself a guest bedroom guest bathroom shower, washing machine, dryer, kitchen, and I'm getting insults so since she arrived the electricity bill skyrocket and the water obviously she's using the restroom the sink the shower the washing machine has the tv on lights on electrical plugs chargers has a private refrigerator.

When I was living here the bills remained the same I'm aware of the electricity bill and water bill I pay for my own groceries I clean up after myself and I'm tired. I'm tired of everyone calling me out like why didn't you clean that's what they expect

So they are complaining to me and I'm not sure what to do I would like to move out but I'm not sure how I'm really feeling like I'm in this situation where I'm not respected I get treated like a child that is financial and emotionally abused and neglected they don't talk to me they aren't happy and they expect me to clean and clean when I want time to myself emotionally I'm collapsing because I don't want them to treat me bad talk down to me glare at me and expect my time off to be fully devoted to cleaning their house this is there house they literally said they will not leave me this house when they die to expect nothing from them everything is to the oldest brother who is married owns his house and I'm just stressed I feel like a maid a servant but I don't feel like a daughter and I don't know how to leave this situation how can I financially make a map to leave this situation.
