Is it normal that I want to have revenge on bullies?

I would say to a degree. Yes, it is. The bully has made you feel less than you are, it's nature but really, what will you gain? You will be a bully, I know saying "rise above it" is useless. As I fully know myself haha, no the best thing to do is either get the said "revenge" and be the bully they call you, or blank it out. Let them, because at the end of the day, who cares if they think you have a baby dick, or that you look like Adolf, (being a Jew BTW, I wouldn't worry. That doesn't annoy us anymore haha) fuck them all. I promise that getting revenge will 100% destroy the already low image of you. Let them say what they like. As for middle school, I'm in Scotland and have NO clue what the fuck that is, so I dunno what age you're meaning.
long story short? FUCK 'EM. They ain't worth it. :) X
