Best thing to do: Laugh it off. When they say those things to you, just laugh in their face. Don't give them the satisfaction of knowing that it got to you. It will just make them feel failed, and it will make them stop. I know that those things can be hurtful, but if they're not true, then it doesn't matter. They're just words. Don't let anything they say get to you. Just laugh it off, laugh in their face, and let them know that they can't hurt you. Good luck. <3
