Harrassment from Father

I am only son to my parents. I am 34 years old. My father has been always abusive physically and mentally since my childhood. Since I started earning, he took all my earned amount and he does not care to give me pocket money. He always used to do emotional blackmail where I had no chance but to give myself all my salary to my father. He has become overcautious and always questions about whom I meet and questions about friends who vist my home. He also abused my mother several times since my childhood. Recently, he started abusing my mother more and when he was trying to beat her I tried to stop, and he started making false allegations of illegal contact between me and my mother. I broke into tears and had sleepless nights and due to 9 years of continous night shift job, I had health issues like unable to sleep properly and I feel my heart racing and I get anxiety. My father won't let my mother meet my sisters. He held my big youger sister's salary. When he made allegations of illegal contact between my mother and me, I left my home and started living separately with 30000 amount in my bank account. I lost my job. I want to know whether I can ask for my earned amount back. I gave approximately 13-14 lacs and he has all that money and I am not expecting all money but at least he could give me what he has. He won't let me meet my mother and threatening my mother to kill if she meets me. We have own house. My mother supports me.
