Mental harrasment by parents

I am a 30+ unmarried woman. My father is 74 years old. Since childhood he has mentally harassed me. My parents used to constantly fight and make me suffer by torturing, beating and verbally abusing. Me and my mother were constantly asked to leave the house. Father never paid any attention to me and my needs inspite of being a govt employee. I was a bright student among first five toppers, yet my father forced me choose commerce, I pleaded him not to do that,fought with him yet he denied and forced me. Thereafter my grades started descending, the situation in the house didn't change, constant abuse and asking me n mother to leave the house. I went into depression, sought help from counselor and psychologist. When father came to know about this he started bullying me that I am a mentally retard,I started failing in career and was tortured more. Since childhood he didn't even give me any expenses and that continued with constant abuse and violence. One day he asked mother to leave the house when she was down with high fever,I asked him not to do that so he started hitting me and even i retaliated.There after it was difficult to stay in the house with constant torture n pressure hence I left.. he constantly had asked me to get married and upon asked if something goes wrong in marriage will he support to which he denied. And when after many years i decided to get married he didn't come to talk to the in-laws, this created many misunderstandings and I am still un married. He doesn't regret even a bit for his actions. Even today i have to go through harrasment for the smallest things.. he never gave me maintenance and blames me for not getting married and having a good career. I am exhausted. I feel like I will commit suicide or kill him.. marriage thing happened recently and I had left home almost 9 years ago.. i suffered depression twice and still don't know if I have got out of it. He is a senior citizen now.. is there anything I can do? He has Denied to give me a share in his self acquired property. Many lawyers told me nothing can be done in this case. Proving mental harrasment and getting share in his self acquired property is difficult in India. Then why should we even speak of women empowerment? My entire life and time has gone in tackling depression, anxiety, fear which also affected my physical health.I lost crucial years of my life, i couldn't do anything properly in my life. I don't understand why I am even born? Why should women even live in India?
