@radioactive45 I hope things have gotten at least a little better for you; if not yet, I promise they will. Hang on in there, and one day you will rise high above all these people who've tried to bring you down.
Side note: a lot of it could be jealousy. Bullies target people who have what they want. Maybe it's that your grades are better than theirs. Maybe you are more attractive than you realise. Maybe they are intimidated by your quiet discipline and focus that they can only dream of.
Think of yourself as a seed. You're in the dark now, but when you bloom into the light it's going to feel amazing.
