How can I file mental harassment complaint against husband and In-laws?

Dear Sir, My husband and his family have harassed me and my family for money. I got married in 2006. My husband is a womanizer and is not interested in having a peaceful marriage. I lost my health in 2006. They have cheated us in all possible ways in this marriage. For giving me roti, kapda and makaan, he would make me a domestic and sexual slave. My father didn't want to own me after marriage and so, didn't my mother. I am not strong enough to do a job. At the same time, he's taking advantage of my weak position and beating me up at home. I am not able to take it. Please help, if you can free of cost
