I'm really sorry for those who will take it badly, but clearly, most of those who respond never where bullied badly. It's COMPLETLY FALSE that if you ignore the bullier, he will get bored and stop. And it's COMPLETLY FALSE either that you can ignore it and get over it. I'm sorry, but you can't. If it's about one kid once or twice telling you names, and if you have a strong social background to rely on, it's ok. But when it's down to the point people keep following you, treathen and ambush you, you have to react differently.
NEVER accept it. The first thing anyone who is bullied must do is to report it. And if the person you talk about starts on the "grow up and ignore them" thing, go see someone else. Bulliing is not just teasing, it's much more deeper and need to be cared about. Find someone who has a position of authority AND understand what really happens. If needed, someone who get bullied can make a kind of journal of the attacks he endures, from the big ambushs and beating if it happens, to the small insinuing comments he hears constantly about him. This can be a main tool to get people understand what his life is. No one can endure such constant insults without suffering deeply, and many people who works with kids regretably don't understand what bulliing is.
To report the attacks is necessary. Those kids who bully others must be cared about, their parents must be informed that their kids are bullies, they must understand themselves that they can AND they will be punished for it. People care more and more about harrasement, at work or anywhere, in the adult world. But many people still think that this is ok from a kid, kids are just that way, it's a normal way to learn how social relations works. Bullsh*t. NO ONE should endure it, and kids less than anyone. AND, other kids must learn from the start that attacking other for the sake of it is NOT ok. But that's not your point as the one bullied.
To fight back can help, when it comes to physical violence. But that will never be the main way to get out of it. Do not let them abuse you without reacting, but do not provoke fights either. You need to find another wat to get out of this cercle.
Mainly, you need to find a niche somewhere, wher people respects you and appreciate you. I highly suggest that you find an activity, preferably outside of the school if you have so much problems with school people. Become a scout, play soccer, learn clarinet in a small band, collect stamps in a local association, become a premium reporter for the studient newspaper, anything you like. Anyone needs to be considered, espacially when they are young. Take it from someone who missed it sorely, and still fight to develop normal social relations as an adult. You will never be able to get over such bulliing if you don't know that somewhere, there are people you can count on. Social interacts are something you must learn, and some people have it easy, and some other don't. But it's always possible to find real friends, if you give yourself the chance to get to them. Bulliers attack people who are vulnerable to them. If you are depressed and lonely, you are an easy target. Having a satisfaying life somewhere, with people you like and who likes you, even as remote as they may seems at first, is a big help to make yourself untouchable.
I don't know what exactly is your situation, if you have some real friends somewhere, if your parents knows about it, etc. But mainly, this is how you will be able to get out of the bulliing circle you are on. Never accept it is the first rule. Find other ways to get recognition you need, and by that mean, prevent them from depriving you from your own life is the second.
It may seem hard. It is. But it is possible to get out. Become the person you want to, not the one they want you to be. As time pass, it will become easier, and you will realise that YOU where worth it.
ps: by the way, I LOVE red hairs!!
