Can you run away? Go to your mother's sister? How old are you?

You must get out of that house. How old are you? Find help.

The only right thing to do is to go to the nearest police station and file a case.
How old are u? If you are very young, then it might be a little hard to convince the police, i.e. if your family speaks otherwise. Just give it a try. Talk to the police.
Where are you in india? I can get you contact details of nearest child welfare society/police station.
Running away is not an option. If your caught/found, things might get worse. Your father's family may start treating you even badly,, they can even convince the society that you are mental,, so do not run away,,
