Family disagreements/ sister edition

Long paragraph sorry 😭 but I’m pissed off So me and my bd fell upon hard times around July and we needed to split ways as far as living arrangements. He stays with his mom, and I moved back in to our family house where my sister and her family (of3) lives. So its just me and my baby that are extras. It’s a 3bedroom house 3bathroom, so it’s really more than enough space as me and my little girl share a room. In the beginning I was not working, but I did provide groceries as I get assistance. Note: I NEVER want to feel like a freeloader, so I will always make sure I provide services of SOME TYPE. Whether that’s cleaning , cooking, or helping babysit. My sister did not have a job when I moved in, she only did hair. Long story short, my sister had already been behind on the bills before I came because my mom and her would argue about it (my mom still owns the house). I got a job to help out, which didn’t last long because I was getting paid under the table and jobs like that never work out when someone isn’t keeping track of the $ 😒😒. But I was paying the light bill with that job before it came to end. Even after the job ended, I was still goin to try to basically beg for it back because I needed it truthfully, but my sister told me to not go back because my boss did me wrong, so I didn’t. But it’s like ever since then, it’s always “you need to buy your own this, you need to buy your own that” and trust me I get it, because money doesn’t grow on trees. However, in the beginning we BOTH contributed to groceries, and now that she has a supervisor position, they turned off her assistance and so now I’m solely responsible for not only feeding me and my little girl, but my niece, and my sister, and her bd when he’s here. Her bd ALSO HAS 2 OTHER KIDS that come over occasionally, maybe 2-3 times a month staying 2-3 days at a time. So I also feed them. Mind you this is my only source of income at the moment. When I needed to wash my clothes it was “buy your own detergent” . When I was using too much tissue, it was “you need to buy your own” . Mind you I watch my niece everyday she gets out of school due to her working, and I have to cook dinner so the kids can get to bed at a decent time. And then I clean up behind mine and her own kids. I just feel like if I can provide groceries for the WHOLE ENTIRE HOUSEHOLD, you should be able to provide cleaning supplies…. I guarantee you groceries cost WAYYYY more than a few bottles of cleaning spray and tissue and detergent. I spend at least 200-400$ every 2 weeks on groceries because if I don’t put the food up after it’s cooked, they will let it sit out all night then I have to cook AGAIN the next day. We waste a lot of food and it’s not by MY choice, but it’s like if I cook, clean, and buy the groceries you want me to put it up too??? Like i feel like I’m just being used at this point. Mind you this job she has, she set her whole schedule up to revolve around me being here to cook and watch her kid. So if I leave today, she would be SCREWED (her bd drives trucks so he rarely is ever home). If you only got the supervisor position job to pay forward your bills when I HELPED WITH ONE OF THEM for 3 months, why are you making me buy all my separate stuff on my own when you want me to spend all my assistance on you and yours. I just feel like I’m being used for my own good. Especially when you have a man that’s supposed to be helping you too. My man will send me $ for hygienic stuff for me and our daughter, like soap ,lotion, he also did buy my detergent once. But I didn’t use the detergent by myself either. So it’s like you want allllll of what I have when I barely have anything when we live in our PARENTS HOME. My parents gave her this house , while I had to go out and find my own apartment spending WAY MORE $$ than she EVER had to on a HOUSE! My mom only charged her $800 rent and she got behind on THAT???? My situation is what it is bc me and my man had a hard time paying 1700$ a month for an APARTMENT , when you pay 800…. For a HOUSE. Everyone’s situation is different, but GIRL! I mean I’m kinda pissed that u want all this help from me when I can barely help myself. Am I wrong for this?!?!
