Those who resort to name calling don't like themselves and they often direct that feeling towards someone else. It gives them an instant lift but it doesn't last so they usually repeat it; it's rather like a sugar rush. The blood sugar skyrockets, then plummets, so more sugar is needed. They're to be pitied and I wouldn't be hurt by her words if I were you. She remembers all too well that she weighed more than you at one time and she's fearful of going back to that old weight. Fear causes all sorts of behavior. Blow it off and be strong in who you are. Words can harm and they can also heal. "Death and life are in the power of the tongue". ~ Prov. 18:21
