To start with, I understand it's not easy to be going through all these at your age. My advice is to find people your parents respect to talk to them.It could be their pastor, Imaam, Grandparents etc. May God guide you.

Ur child should be a product of love and not because a parent want to play God. A lot of fathers now will their properties to their female children and even grand children. Pls,don't give in to their demands

My dear,pls stand ur ground. U are very young to be involved in this. Go to older members of the family e.g uncle,grandma,grandpa and state ur case. Pls don't give in,they shouldn't meddle in ur life bcos they feel theirs is not perfect. If they insist,go to social welfare ministry in ur state, they will protect u and the govt will restrain them or u get a lawyer.
