Put yourself in the mean girl’s shoes. You might think that she’s the most confident person you know, but that’s typically a front that mean girls put on. Usually, mean girls have deep rooted insecurities and/or problems going on in their lives. While this doesn’t give them an excuse, realizing this may help you understand that their harassment isn’t about your flaws, but rather about their problems. If you get wrapped up in the mean girl’s comments and actions, you may become bitter and have a hard time keeping the meanness from negatively affecting your life. Consider telling the mean girl that you forgive her for what she’s said and done and asking her if you can start fresh. You can also move forward by keeping your forgiveness to yourself and focusing your energy elsewhere. If you’re being harassed by a mean girl, you aren’t the problem, she is.

It’s hard to be positive when she’s being so negative, but it’s important to remember that you are a person with value. If you’re struggling to feel happy and confident about yourself because of the mean girl, try to:  Keep a journal about how you feel. Think of three good things about yourself whenever you’re stuck on one bad thing she said about you. Do activities that you enjoy and that make you feel good about yourself. Don’t try to deal with bullying all on your own. If the mean girl won’t stop harassing you, talk to a teacher, parent, or guidance counselor about the things she’s saying and doing that hurt you. You can also talk to your friends about how to handle it. If they’re willing to stand up for you, the mean girl may not bother you as much. Invest in the solid, stable friendships you have instead of constantly engaging in negativity with the mean girl. Go do fun activities with your friends and make good memories and bonds with them. This will help you feel more happy and secure.

Try to understand her motives. Forgive the mean girl and move on. Work on loving yourself. Reach out for help and support. Spend time with your true friends.
