Harassment by step daughter n her father

I am 60 years married to a widower with a step daughter (who has been adopted by him.n his first wife) in August 2014. My parents are no more n siblings are to themselves. I stopped working after marriage and supported the step daughter in her education. The step daughter does not want to work and getting her father spend all his savings. She is disrespectful to her father and to me for the FD deposited in my name out of which I get a very small amount from past 7-8 years harassing me physically, mentally, verbally n playing a dirty game where the father blames me saying thaali dono haatse bhajtha hain. They both want money and she is trying to throw me out of the house by behaving badly in the absence of the father n pretending innocence in his presence. Both father and daughter want me to earn n are behind me for the money deposited. He is not agreeing for mutual consent nor to separate for various reasons as there is a property in my name in my hometown. He wants control of everything n treats me very badly. They want me to go away without a divorce. Things are becoming very worse and I have no mental peace n got bp due to all this stress. Constant harassment by both of them. Tried to resolve by intervention of psychologist, his brother-in-law n my brother, they pretend innocence n made me the accused by saying all wrong things. Please guide me as they won't hesitate to get rid of me.
