Help with protecting myself...

Oh, and if your scared to go to the police try telling a teacher at school during lunch or something and she will do it for you.

Go to another relative. A father, uncle, an adult who will fight for you. If you have bruises or marks, show them, if you can get an audio recording of them attacking you, or leave your webcam on and recording in your general direction with the monitor off. Get proof, then go to a relative. When you get there have them call the police. Make sure the relative is willing to let you live with them, or if you are 16, help you become emancipated.

Calling the police without proof can lead to them doing absolutely nothing, especially if your mother is a good liar. You want it to be undesputable evidence.

There is a spell of banishment that I can think of, having to do with getting a personal item and floating it AWAY from your house. Or make a chamomile tea and put some of it into the drinking water, or banishing botanical concoction and putting it in the drinking water (make sure it is edible) though I would consult your spirit guide before any action.
