I am 20 and just moved out of my parents home because my mother is mentlly ill (and is too much for me and my sister to take care of.) And my father is a very mean, verbal and mental abuser. My sister who is 16, does not want to live with them because of these reasons. My parents home is not a stable environment for her. I would like for her to live with me. Is there anything I can do to get her?
