Today a Hawk that lives next to my home swooped down and clipped my head. I have children. What do I do Help?

This hawk has a nest in a tree next to my driveway. I do not have a bird feeder or any reason for it to lerk here. I am afraid for the safety of my kids, and myself. I can't do yard work and my kids can't play in the yard. How can I get rid of it?
