What you do when you have bully problem?

I took up martial arts and punched them in the nose. It's not the ideal solution, but it works.

Either stand up to him/her or turn the other cheek, but don't let the bully see you sweat and don't flinch.

Grab a kitchen knife and bring it to school then when you see the bully dig it into his heart and murder him

Bullies are nothing but evil, depraved monsters who are usually too fucking stupid and retarded to get anything meaningful accomplished in our world, so they resort to attacking their superiors (which is anyone who isn't mentally retarded) out of jealousy and hatred.

No one has to tolerate that kind of shit, and simply facing it is useless and stupid. All kids who are being bullied need to fight. The only physical fight I've ever been in was with a bully in 7th grade. He attacked me first after almost a year of physical abuse and torment, and I let him have it the hard way. He ended up unconscious, with a broken arm, broken knee, three broken ribs, and a busted nose. I had a large rock in my hand, and was tempted to smash his skull and kill him, but forced myself not to and called an ambulance instead. Luckily, I avoided criminal charges due to camera footage showing it was self-defence.

For the kids who don't want to "get in trouble" for fighting a bully. Listen to me. I am 4 years out of high school, and already more successful, wealthy and accomplished than most people will ever be in their lives. So getting in trouble won't hurt you too much, only the bully will.

If you want it to stop, you are probably going to have to take a beating. It sucks, but that's life.
Every so often someone in their 20's comes on speaking of how the bullying has screwed up their lives, even long after it's over. No self respect, no self confidence, social anxiety, etc.
All ridiculous as their bully(s) shouldn't have that much power over them for so long, but that doesn't change how they feel.
So, get it over and done with. Give as good an account of yourself as you can, but stand up to the asshole even if it means a bit of pain. He should leave you alone after that. If he doesn't well, there's always a 2 X 4 some evening, to even the odds.

I also suggest that you talk to your parents and teacher or principle. Being bullied is really not nice, it happened to me too.

I know about bullying very well. I took a lot of punches
in elementary school, middle school and high school. You
have several different options here. First off, you could learn to fight by taking martial arts classes. If you're being bullied at school, you can talk to your father. or the principal of you school. Or you could stand up to the bully and tell him to leave you alone. If you choose this option, you need to look him straight in the eye, think your angriest thoughts, and shout for him to leave you alone. Or you could go to this website: http://www.wikihow.com/Stop-Being-Bullied. Good luck!

That's a tough one.
There was no intervention in schools when I was growing up and I learned to let people say anything they wanted to about me, but when they laid their hands on me I would completely lose my shit, climb them like a tree, and do my level best to make sure they felt as sore as I knew I was going to feel the next day.

We moved a lot and I would 'usually' only have to do that once or twice per new town before the bullies just left me alone.

Best of luck to you.
