Want to be emancipated

Ever since my mom left her husband we lost our house and now we living with out grandma but we have no rooms we sleep in the living room and for a while I was the one that has a job my mother did not and i would help her with money when she needed it but it became too much because I needed the money for clothes food and my phone bill and it didn't help that money kept going missing from my wallet. She hasn't been around the best of people. And my dad has said things to me that a dad should of never said to his daughter telling her she made too many mistakes that he disown me and he has said it twice in the same year and I'm struggling in the school I am in now and would like to move in with a friend and go to the Glen rose high school because I have looked and looked and Glen rose is a small school I'll b able to focus and get the help I need there and my mom promised me she would help me but kept me from going to school because I would wait on her to show up to turn in the papers and she never showed up and than told me she never was going to do it so I have missed a week of school bc she lied to me
