My "Friends" Constantly Bullied Me And Refused To Stop. Any Advice?

So I'm in 7th grade and starting last year I've been wearing bucket hats ever since I cut my hair very short. Lots of my "friends" and other random people in the hallway took my hat and threw it on the ground, or refused to give it back to me. I've told them all to stop multiple times and they never do. I come home crying every day and this year I don't want to start any arguments with anybody because all it does is make me anxious and depressed. Any advice?
