Domestic Abuse against minor

I am a 16 years old girl and I am suffering from regular domestic violence. My father is a characterless creep who will click my pictures and distribute among his friends and my mother is having multiple affairs. They moved me when i was child to my grandparents where an uncle tried to abuse me. There are multiple cases which I can't illustrate here. Now when i wanted to get help and even tried to get out of this hell, they try to control me and even even physically torture, lock me and even stop my access to internet and calls so that I can’t call the police or the child helpline number. Still I managed to call once and although the police threatened them they stopped for some time but now they have restarted the torture again. I feel unsafe and don’t want to have any communication with them. In this regard please help me with the following questions: Can i stay alone while claiming maintenance from them Is there any way to make sure they or any of their known people don't try to harass me. If I stay in a government house can i use internet to complete my studies through distance education or any nearby colleges After I turn 18, how soon can I leave such a government home. I don’t have any means to pay any lawyer. How do I contact and file the case? It will be of great help if an urgent help is provided. Thank you.
