I am in a trapped, hopeless situation. Help, please?

My family and I have been looking for a place to live for a year. We are currently living in a spare room with my controlling, emotionally, and psychologically abusive uncle. (My mother, teenage sister, and me.) My sister sleeps on the couch, and me and my mother share a twin air mattress despite my bad case of whiplash in my neck and my mother's very painful arthritis. (She can't take meds for it because of allergies and severe stomach problems.) She has a job, but I have been laid off. It is barely enough money for the three of us to eat, let alone pay rent somewhere. We have been thrown out of my childhood home by my grandparents, who now keep thier possesions in thier home and our old one. They hoard garbage and needed a place to keep more when thier house became too full. The house was in thier names, so legally, we have no rights to our home. My mother owns a small piece of land jointly with my grandparents, who refuse to let her sell it to help get housing for us. Her "ownership" of said land keeps us from recieving benefits such as food stamps, HUD, or medical insurance for my younger sister. We have one car between us now, as I had to sell mine to pay for food a few months ago. When my mother takes it to work, I am left alone with my uncle, who harasses, yells, belittles, threatens, etc. I feel trapped, like there's no way out. We are not allowed to use his washer or dryer. We cannot cook meals here, either, which means we waste money by having to eat out when there is a perfectly good kitchen here. We have no savings, no relatives or friends to turn to, and it feels that there is no way out. This is a smallish town and there is no work available. I am doing my best to keep things together, but the stress and depression make me physically ill, usually on a daily basis. I've lost ten pounds in the last month. I can barely keep food down. Does anyone know of any way I can make money legally to help dig me and my family out of this terrible situation? Or just some words of encouragement or prayers? Thank you.
