I don't know, I mean if they are bullying あなた then just tell someone, but it could also mean they like you? Maybe? If they are you're フレンズ then that's normal sometimes, but if it is really affecting あなた and they are being jerks about it then tell somebody.
Are あなた a girl if あなた are it might be because they might like you, または if your a boy they might be jealous of あなた または just want to bully someone, don't beat them up または anything maybe just say something like "leave me alone" または tell a teacher または an adult they will handle it.
