My experience with bullying

I got picked on and laughed at for many years by my classmates. Nobody was a good person. Of course I paid them back in the sweetest way. Befriended them to reduce it a lil and caused fights between them bc they thought i was dumb (ops) and dropped them when we went to high school to find a real friend .They had nobody else, got separated and i wonder why that happened? Karma is a bitch and they were begging me. I never lost confidence even when I was literally shaking because of them. Now if someone tries to bully me, I laugh at their face ╮(￣▽￣)╭. It happened with two girls, one in high school and one now in uni. They are really pathetic. They are laughable and so pitiful. Not worth my fear or anger.
