How to cast a protection circle spell?

[Nina]

Hey guys

I really need help... today my brother and my father beat me, and I dont know how to deal with that cause I cant go to police. I really need a strong and simple protection spell, something that will harm all that want to harm me, and protect me from evil people.

Please guys, help me!!!
