Living with dumb family members who are greedy, controlling, selfish, and users

I own a house with my mom and she wants to control the whole house like it's hers and thinks I can't do anything to have control of any of it and had me and my brother live in one room together and had me pay an unfair amount without even doing calculations. My mom got a room to herself and my sister also did and my sister still had a room when she wasn't working and my brother wasn't working either for the most part. If they don't work, my mom should be responsible to pay there fair share, not me and her together, since she let them stay and I didn't agree to it. I finally got the room to myself, but the bill was still unfair and my sister moved upstairs and my brother with no job also got a room to himself. Another brother moved upstairs and another brother, his 3 kids, and his girlfriend moved in with downstairs with us and my mom had me move in the living room with the brother and it was shared and other people that lived downstairs used the living room also and my mom still had me pay an unfair amount. My sister moved out eventually and I moved upstairs while the other brother, but the bill was still an unfair amount. My mom had me move back downstairs eventually and the sister moved back in, I had the dining room, but no privacy a lot of times and the bill was still unfair and also, my moms stuff was in the dining room too. Now I have a room to myself downstairs, but my moms stuff are also in the room and her two annoying dogs that are not my responsibility when she wants me to take them out and do other stuff for them. She also tries to have me take out the garbage and take out the 2 other dogs that are not even mine or hers. I am lazy a lot and don't do my dishes a lot, but y should I help then at all when I get treated unfairly and used a lot though. I shouldn't have to take out the garage a lot, when others use it too and she is not the boss of me, but she is bossy a lot though. My brother and mostly of the people that lived downstairs used with me apparently believe that it I'm not paying enough and I don't own the house and have no control, only my mom and my brother believed that he has more control over it because he pays more, which is the electric bill anyway, I only payed for part of the mortgage. My mom made prices of who pays what and how much, they are dumb and that's not how it should work, it should be spit fairly of everyone who lives there and who uses electricity and stuff, not just me, my sister, my 2 brothers, and my mom. The kids should count and his girlfriend and my other brother that has no job. He had no job for more than 2 years and lived here for free for the most part. My brother that has 3 kids and a girlfriend doesn't pay enough, but believed that his kids don't count because they are kids and can't pay for anything or whatever, but they still should count and he should pay more oth the bills for them though, the girlfriend doesn't pay anything to stay here either btw. My brother also believed if people that can get a job, but don't have one shouldn't count for the bill split either or whatever though, but they should and I shouldn't have to overpay if I don't agree to it, etc. though. My brother that has no job also thought I owed him because he gave my mom his whole check more than once to help get the house and he thought that it's more his house than mine or whatever though. No it's not even his house at all just because he paid more than 2000 on the downpaement or however much and thought I payed nothing on it, btw, I didn't even have him pay anything for the down payment, my mom was being a jerk and wanted everyone to help that was apparently going to move in or else wasn't aloud to if they didn't help or whatever. No one should have even paid for the downpayment, especially for me and my mom, since we are on the deed. I actually did pay more than 1000 on the downpayment though btw. Also, he broke at least 2 of my phones that was worth more than 3 or 4 thousand combined if they where new and he lived there for more than 2 years without paying anything anyway, so he was being dumb and being a jerk because I brought up that he lives here for free more than once or whatever and he didn't like that, he and the brother that has kids apparently think what he does, like taking out the garbage at times, the dogs that are not even mine, watching are brothers kids at times his good enough to stay here without paying anything or whatever, but no it's maybe not even close. It's not worth staying here without paying anything and it's maybe hard or impossible to live here for free if you do stuff for people because who should do stuff for everyone that pays the bill, not just for certain people though. So he shouldn't even be staying here, especially since he doesn't even want to pay if he did get a job, unless my mom needed it or whatever though. I did get free meals and whatever a lot and I don't pay for toilet paper and stuff and certain people don't pay certain things at times also, but still, even then, I still overpay and the bills like garbage, electricity, mortgage, etc. not including toilet paper and stuff should be calculated and split to a fair enough share out of everyone that lives here for the most part anyway. Plus apparently I owe my brother that has kids and my other brother that lives upairs a lot because I lost my job and didn't pay anything for at least 2 to 3 month, but I downt owe them anything technically when I been overpaying for more than 2 years and it was my brothers choice that lived upstairs, but is away for work for more than a year or however long to pay a lot to keep up the mortgage and the electric upstairs. Please let me know your thoughts and if you agree with me on anything or not. Also please no mean comments, if I see any, I might reply to everyone I see and be mean to whoever posts it report them and maybe eventually delete this post eventually also though. My bad if anyone doesn't understand certain things I typed though. Please don't try to correct my grammar and spelling if anything is wrong also, it's a post, not something for school or work anyway. This is not a full explanation of the whole situation that happened for more than 2 years, but maybe should be good enough though. Please just try to be nice in your comments, please and thanks.
