I have a friend who is like the main mean girl in the movie "Mean Girls." No one really likes her and she's so mean to everyone, me especially. I
tell myself day after day that I need to stand up to her. I need to tell her that she needs to stop making those snotty comments and rolling her eyes at me, but whenever that opportunity arrives I can't say anything. I'm beating myself up over this so will someone please tell me what to do?
