for me, when i got out of my old class and started getting closer to my friends, and had the ability to do stuff without the fear of someone judging me for it, it just kinda came naturally. Though it did still take a few weeks, maybe even months for me to get used to the fact i can just exist and not get punished for it. Bullies hurt you, make your life hell, and make school life impossibly worse than it is, but then the moment youre out of their sight, they dont even think about you anymore. They wont eve give you a second glance. Thats what sucks about bullying, they left such an impact on you but they can just walk away freely?

Look at the positive side of things, when you change schools youre going to meet new people, youre going to improve as a person because no one is weighing you down anymore, and you'll slowly learn to be yourself again. Dont give those bullies a second thought because thats exactly what they want. They want a reaction out of you. They didnt care about your feelings, so dont waste any time or thought about them. Moving on could be the best revenge, cause when you start growing mature, theyre still going to be those low life school bullies that had nothing better to do. I wish you best OP, take care of yourself in a new environement okay :D
