Fightin Back Question 13m

I have a question about fight back toward people. If someone hurts or harms me, do I fight back, tell authorities (aka teachers or adults), or do nothing. There evidence for each of these. I think do what someone does to you but also we are not supposed to be violent. If I snitch, I'll feel weird and out of place. And if I do nothing I'll be letting God give revenge or payback like we're supposed to do. In this scenario, what should I do?
