I Need Help With My Abusive Grandmother: I Cook for her, give her her pills, clean, and answer to her every whim while also going to school.

Hello My name is Joshua and I am 17. I need some ones help and advice desperately. You see my mom has always been their for her parents. My grandmother her mom was abusive to all of her kids. My two uncles don't talk to one another and have their own problems from their child hood, my aunt is a textbook definition of a narcissist, and my mom has had her own emotional damage being picked on and abused the most by my grandmother. Anyways my mom always helped her parents. My mom would come over and help my grandfather with physical labor while my aunt (who by the way was living with my grandparents rent and utility free) would sit and do nothing to help around the house. I even at the age of 4 and 5 would do my part. I loved my grand father so much because he was the father I never had. I had to watch him slowly descend into despair through Pixes Disease. The man I loved so much and the one who protected me from my grandmother's abuse had died in a coma when I was in 5th or 4th grade. It was like losing a father. The worst part was he would cry for my grand mother when he was in a nursing home for about 4 months before he died, and she never came to see but once. My aunt would walk in sign the guest sheet and would leave. When my grandfather died my mom and I moved into our current home to take care of my grandmother. We then and still to this day pay half on every unitlity, grocery, and the house payment. My grandfather, grandmother, and my two uncles all wanted my mom and I to have the house, so my mom was put on the deed. My grandmother ever since we moved in, back when I was in 5th or 4th grade has been a nightmare. We have had to move out of the house several times. The first time we moved over to my aunts and then she took all my moms money and other belongings. My grandmother was acting all sad that we left so we returned. Things were fine for about a year or two and then she went off her rocker. She calls me names like "bast***" because I was born out of wedlock, "leach", a "lair", and much much more. She will even push me some times. I will cry some times because I don't get it. I try so hard to take care of her but she treats me so badly. One day she is nice the other she is mean. She always thinks my mom and I are conspiring agents her and she thinks people are in the house and do stuff to her. She falls all the time and i pick her up. Some times while I pick her up she makes fun of me or calls me names. When I tell here no one is in the home she calls me a liar and does not believe me and gets mad. About two years ago she hit my mom in the face and we moved out. About two months later my aunt cohurest my grandmother out of our home and told the police my mom was put on the deed of the home ileagly. This was not true and proven not to be true, but my grandmother abandon the home for 2 months. My mom moved her and our selves back into the home and my mom paid for the moving expenses, the money to catch up the house, and the penalty for breaking our lease. Things went good for about a year and the same things started once more. This time my mom had enough and told here that scene my aunt was involved and you have no respect for me and my son let her take you shopping and you stay on your side of the house and we will stay on ours. You see our home has two living rooms one on each end of the house. My grandmothers master bedroom is connected to one living room and my and my moms rooms are connected to the other living room. The kitchen is in between the two living rooms. So it naturally splits the house in two. She how ever did not do this. She would walk over onto our side of the house and call me names and start trouble. One time she sat down next to me and said hi whats up, she replied with nothing i'm just trying to aggravate you. Then my aunt after a month of talking to my grandmother wrote up a false TPO (using her counseling experiance) saying my mom abuses my grandmother and my grandmother not knowing what it said signed it. I was kicked out of my home under false pretenses for about 4 months. The judge at our hearing knew my aunt and did not let my mom or any of our charactare witnesses speak, just my aunt with no evidence, proof , or witnesses of abuse. He extended the TPO for a year. During the first months of my mom and I being gone my aunt made my grandmother abandon the house once agean and while living with my aunt my grandmother would be forced to clean and cook. My grandmother says she felt bad and after a family friend talked to her she met me at the court house and the TPO was dissolved. We are all now back in the house me, my mom, and grandmother, and things are starting up once more. She calls me names, is paranoid people are in the house doing stuff to her, saying nonsense, and falling. What do you thing my grandmother is doing and what can I do to stop this craziness and give my mom and I a peaceful live and my grandmother the help she needs.
