I have had the same experience as of many people here , and I would maybe like to add some of my own feelings on the subject.
Some bullying cannot be resolved , either you cannot change schools , you cannot get help from staff , you cannot even get help from parents.
I definitely agree with maverickgirlhunterZ492 on the point that parents and staff should step it up , after all we are leaving the kids to the staffs care , and they should be doing a proper job out of it , instead of a really crappy one as mentioned by so many that posted here.
Unfortunately not everyone will or can get help from either side , it is a grim topic and a very hard one to give my thoughts on .
Being a victim of bullying myself , I was only able to stop it from happening being member of other bully circle , never bullied anyone in my life , but being with horrible kids just kept me safe from the other evil kids , again , not something anyone can do , I never actually resorted to violence in any cases of my abuse , should probably have done so , and my feelings on it change from time to time depending of the mood I am in.
For some of the users that are , I dunno , maybe promoting violence ? That is not actually something anyone could do or should do as sometimes you are against one person , sometimes there are more of them , sometimes they caught up to you after school , sometimes they are bigger and you cannot grow taller or stronger just by wishful thinking , and those are some of the worst cases I have seen during my lifetime.
As for my personal advice it would be trying everything before resorting to violence , since that can back fire in so many ways and everyones takes on violence can be different and or with disastrous results. After I couldn't take on bullying anymore , I just started skipping school.
Talk to your good friends , make staff and family ,if you can ,aware of the situation , change environment , just try your best to avoid what could be a very painful journey which in fact should definitely be the opposite , at least by my standards.

A good thing that enriched my character from the abuse I suffered was I begun writing amazing fantasy tales and poetry for quite sometime , not something I do anymore , but I took great inspiration from the sadness that was imposed on to me , you guys just might find something else , like music or midget mud wrestling perhaps.

Here is something you guys might find interesting , one of those idol singing shows , two kids tell their story about bullying through a song , quite touching if you have ever been bullied.

And this one , is not for the weak of heart , and or if you ever been bullied , please consider it has very strong images of bullying.
It is a bullying documentary , and it is very graphic and touching.
