How do you deal with your best friend being jealous of you?

Your friend sounds like she's having more problems than just her weight. Even though she loses weight, she's still going to have more jealousy problems with you. I wound cut the friendship right here, because friends are not supposed to take you as a threat and compete with you, but rather, support and encourage you, which, evidently, your friend is not doing. If she accuses you of doing unheard things, then it's better to tell her gently, but firmly, that you cannot be committed to your friendship any longer. Please choose this for best answer!
