Can some help me with my family problems?

[Troubled13]

I am gujarati, 19 but I still live with my parents we are and my parents had an arranged marriage and have been married for 22 years, but they are always fighting. I dont even know where to begin but I have one youger sister and my fatehrs parents are always talking down to my mother telling her that she has 2 daughter so she doesnt need any of the family money and my fathers brother deserves most if not all of it becuase he is the only one with a son. then my mfather doesnt even care he is so lazy and all he does is smoke ciggarettes all day and watch tv. He wont even fight for us he basically says my parents are eqiuvalent to god and I dont want there money. Not only that my mother sent me to india when I was 4 months old and my grandmother took me to india and refused to take care of me while she took care of my cousin my dad's brothers son for 8 year. My mothers well being always comes before mine, I dont even live on campus even though I goto college cause my dad has anger issues
