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