How can I stop being so worry?

When you feel sad, it can be pretty hard to pull yourself out of it. First up, don't tolerate your cl mates being mean to you. Call them out on it, being ertive will boost your confidence, and confidence scares away sadness and bullies for that matter. Do you have any hobbies you like to do? Concentrate on things you enjoy, and things you are good at, that will be sure to lift your spirits.
