How to I resolve this?

My parents are always torturing me since past 13 years. I was in pew school about 5 to 7 years old and my parents left me in my cousins house where he had raped me and I wasn't even aware of what he was doing and I never told my parents about it because they always told me to obey elders I kept pushing him but he was too strong. He was born in 1994 or 95. I still remember those times when he was continuously raping me in the name of playing with me and my parents had no clue about it. That had become a trauma and kept feeling strange sensation in my body throughout. When I was 10 I couldn't study well and score good marks like my cousins I am a average student and my parents kept scolding me for not scoring such good marks and always hit me with a stick so bad that I was bruised. But still I couldn't score more which made them to start comparing me with my cousins and they started telling me that I'm ugly im not as beautiful as my cousins and I never made any friends because my father told if invade I did make friends he would kill me and he doesn't care about going to jail and also mentioned that his reputation in the society is great than our lives so I never made any friends and people at school kept bulling me till class 10th. As a child I had to endure all this and move on. When I was 16 years I went Nagarjuna school where the teachers and the principal kept torturing calling my parents and giving them false statements like I was always with boys. They also made me stay at school till 8pm because I wasn't studying. My dad kept scolding me he never believed me but he believed those people who kept complaining false about me. That's where I started developing a pain at the back of my head and chest pain because of my parents cursing me everyday. In 12th I was changed to Nitte college and I got to make friends there. One day my parents got to see a picture of me with a male friend and I was belted till I was bleeding.. my college principal had to cut the dress because the dress was stuck to the wounds causing a horrible pain and had wanted to speak to my dad personally. I expressed how the treated me since childhood and they advices him. Ever since then he changed but now at the of 22 and 23 he's back to the way he is and my mom n dad keep cursing me they don't let us sleep they throw their phones at us if we delay a small work and they throw their slipper and come to hit us if we ever speak back to them. I was 10 when I wanted to suicide because of my parents but I never knew even now at the age of 23 I'm trying to take sleeping pills antidepressants or any other alternative to just die rather than being alive and staying with my parents. I'm scared to go to the police and tell them about my rape case and my parents and I'm also scared that my parents would kill me if they knew that I was raped. I just don't know what to do. I just wanted to suicide because of their trauma depression my health isn't good.
