Just Tell Yourself:
I'm annoying, I'm fun, I'm cool, I'm strict, I'm bossy, I'm bratty, but I'm me and that's all I need to be!
I don't need people who make me feel bad, and I don't need people who hurt me. All I need are the people who I love and the people that love me back.
I'm amazing no matter what anybody thinks, I'm cool no matter what anybody else says, and I'm awesome no matter what anybody else does.
