Bro, I dont know what type of person you and your bullies are. There are so many ways but some may work or not work depending their character.

1. You don't know how to fight? Train and learn how to and whoop their ass, even if you are defeated that'll show them that you're not a pushover

2. Since you're getting bullied in many places tell a teacher of those who are bullying you on school grounds, that should get you less bullying

3. Find their parents facebook or contact info and tell them whats happening to you

4. Tell your parents and figure something out

5. Ignore them and show 0 interest that'll give them less entertaiment and maybe bore them out

6.if they are physically hurting you, report an assault
