What works is to no longer respond to the bullying the way the bully wants. Being upset and angry – is an emotional response. Your anger, may actually be rewarding to the bully. That’s the first reason to not allow your anger to consume you.
Bullies are humans too and have their own problems. Plus, hate doesn’t help us deal with it or make the unwanted behavior stop. And, hate doesn’t feel good. Hate is triple plus bad.
