I was bullied a lot in school, in Elementary, and middle school. In elementary I fought back (Physically) and he left me alone, in middle school a new bully, but twice my size. I had to just ignore him, and he died down a bit. You can't take it to heart, all my bullies were black, but i'm not racist, I was tortured but never tortured.
Bullies simply lack humility, simple as that, so if you are strong enough, teach them, if you are not, well then live with it. This is the real world you can't tell anyone, or it will get worse, you can only fight back, or ignore. Life is better outside of school though, adults don't act like kids in high school (For the most part). Good luck.
