Contact the Mobile County Office of the Alabama Department of Human Resources and ask them to open an investigation.

Your conversations with people at school who are mandated reporters of abuse and neglect, should have resulted in a report to Mobile County Office of the Alabama Department of Human Resources. Since you have been to court about your mother's abuse, it sounds as if DHR did open an investigation.
If DHR was not able to convince a court to place you and your brother in protective foster care as a result of the abuse, the only other solutions would be for a local adult to convince your mother to let you live with them or for your father to try to get custody transferred to him.
This is not something that the kids are supposed to have to deal with on their own, but try Atty. McBay's suggestion of calling DHR and see if they have other alternatives for you. If it doesn't rise to the level that DHR is going to help you move into a program or protective foster care, the only other options are for caring adults in your life to seek a resolution through a change in custody.
