I had a similar problem two years ago and I was so depressed to go to school knowing there were those people around. I'm suggesting this only because when I told them in a very harsh way they were pissing me off and they were such stupid and ridiculous beings, they thought it was a sort of joke, I suppose (they were not clever enough to understand I was really angry with them or they simply found it amusing) and they started laughing and things went even worse after that day. When I started to ignore them and I wasn't looking at them with an angry face anymore, they didn't find it funny and they got bored after some days. They started bothering my classmate and even if I was sorry for her, I was satisfied with myself.
