Fighting back was the only thing that stopped the bullying for me, at least for a while. I decked more than one kid in high school, which usually gave me a few days/weeks reprieve from the worst of it. (the worst being two or more kids kicking and punching me in a corner/on the floor) I never fought back for revenge, I just wanted it to stop. Ignoring them never worked. Going to the teacher was counterproductive, because the teachers did nothing and the bullying becomes worse because you're a wimp/girl for "telling."
Luckily for me, my family moved to the other side of Melbourne when I was about 17 and I changed to a new school, which had good teachers who kept bullying to a minimum and didn't do victim blaming - at my old school, I don't remember single time where I wasn't suspended/given detention/given a stern warning for defending myself. A lot of the teachers were basically bullies themselves.
