If this happens to you, here are a few things you can do.
1. Spend any free time with your friends. Bullies hardly ever pick on you if you're in a group.
2. Tell the bully to stop and walk away whenever the bully starts his/her tactics. Be as stern as you can be to make sure that (s)he knows that you aren't kidding and that a no nonsense message is passed on.
3. Tell a trusted adult about the person's bullying behaviour. This isn't telling tales. This is about keeping yourself safe, which is of ultimate importance if you're being bullied.
4. If you can, try to act as if you are unaffected by the bully's tactics to undermine you. This could dissuade the bully from persisting because bullies love to see you upset. If you appear not to be upset, some bullies may stop as there is no more incentive for them to continue.
5. Don't lash out at the bully, either physically or emotionally. Instead, stay strong and walk away. Otherwise, you may be accused of being a bully yourself.
6. Bullies are usually angry people. So, it's best if you don't reciprocate a bullies tactics or attitude without support from others. If in doubt, just calmly walk away.
Just because bullies are all around, doesn't mean that you have to tolerate bullying behavior or actions. The best remedy for bullying is to stay strong and focused and walk away as if you are unaffected. Bullies hate that!
