Parents Brutal Violence

I was 27 old, loved and eloped with a man. I'm from a Tamil family. I realized my mistake. But my mom gave a false complaint to Indian police that I stole all her gold jewelry and ran away. Indian Police caught and hurt me. My mom took me to her house and her own sister bought two unknown men and started brutally torturing me. My mom was sitting on a chair watching me getting me tortured. They brutally beated me with a rod, tore my clothes, stamped me, made me to bleed on my nose and knees, my own grandma plucked my hair and threw away. Her sister was stamping my vagina saying that I am greedy on sex and I was wanting to lick the penis of the man with whom I ran away. My mom didn't stop anyone. They took my certificates, passport and my belongings and locked me in a dirty room for a year with no contact with anyone. I had no food for continuous three days. Everyday they used abusive words calling me a prostitute. I used to get food only once in a day for a whole year. Several days when I sit in the toilet I never use to get normal excretion. Only tiny droplets used to come. I cried a lot. They treated me as a slave dog always abusing me with no humanity. Till the day before I got married I was tortured brutally by her sisters. I wanted to be loyal to my future husband. So I told the truth to him by phone call before marriage whatever happened to me and the reason behind it. My mother was listening to my phone talk and she told her sisters and they took a wooden bar and hit my head hard. Only till that I can remember. Later I totally became mad and mentally unfit. He got shocked the day before marriage that I became mental. But still he never gave up and married me. He got angry and planned to sue everybody. But they apologized and gave back my belongings to him. Right away he took me to abroad and we got settled. He admitted me in a psychiatric clinic and diagnosed with PTSD, I was in sedation. I got treated well and came out of mental illness after a year. It's been 4 years since this happened and I'm unable to forget. I hate my mother and her family to the core. I blocked everybody's contacts and decided to not look at them anymore in my life even if they die. I hate going back to Tamilnadu. Even today I can't remember what happened during the day and after the days of my marriage and how I reached abroad. He showed the photos of our marriage and then only I realized I got married. I really feel blessed to have a loyal Husband. Everyday I'm getting those bitter thoughts and ruining my life. Currently I'm pregnant. Unable to have peaceful sleep. Please someone one advice me to get rid of my past bitter experience??
