Since you appear to get along best with your dad, ask him for a copy of the custodial order or any agreement concerning child custody. Tell your dad that you prefer to live with him, and he will likely go to bat for you. But, if the court has already declared otherwise, it may be difficult and/or expensive to modify the order.
You can also request to review the court's file for the child custody orders.
As Mr. Erikson said, ask your dad for the court orders. If he doesn't have them, he can get them from the court. If y'all don't know how, contact local family law attorney who will likely speak to you for free and hopefully clear some things up and point you in right direction.
