Moving alone with no support and difficult family?

Hi, I posted this question in the wrong section earlier. I just turned 26 years old and am really miserable, depressed. I grew up with an alcoholic father and really angry bitter mother which caused a lot of dysfunction. My sister became mentally ill because of all the stress, my brother got into a lot of trouble when he was younger. I just stayed quiet and tried to be good. They don't speak English and relied on my on paying bills, translating, and etc. I worked and went to school fulltime and managed my parents finances along with my own. My dad stopped working and went on disability my mom was already on disability and my brother was not working. I had enough I took a semester away all the while my mom would put financial pressure on me. I came back with no intention to stay and go an internship that turned into a job with my own apartment but that wasn't good enough for my parents and I didn't like my boss so I moved back to help them and try to find something better. As soon as I moved back I realized why I left I moved out of state again while trying to "make it" on my own and handling all of their financial obligations. Then they taught my dad had lung cancer so I moved back to help them again and take him to the doctor's and etc. because he didn't want to go, turned out to be nothing. I'm in a job I hate, my mom puts me down, and now I'm financially strained. I don't know what to do I'm so miserable. I started seeing a therapist she says my mom is emotionally abusive she insults me, any friendships I've had, lists my failures, and put her financial and marriage problems on me.I have no where to go no sympathy or support from my sister or brother. I want to move but I feel so alone and I don't know if I could do it again I'm so emotionally drained.
