I want revenge. I'm afraid to see anyone because of one person.?

Don't think about revenge. Be the better person. Take comfort in the fact that God will judge her someday. The Bible says we should love our enemies. Pray for her. Get over it. Everyone will forget about it in a day or two. And the people who heard her do this know she is a creep. She's the one with the real problem. Forgive her but avoid her from now on and be more careful about choosing friends.
