Ask friends not to agree with you
My belief is that the worst thing a friend can do is to meet you at the level of your jealousy. Agreeing with you that the envied person is, in fact, an undeserving bitch. Or even saying, “Well you’re better than her anyway.” These things don’t heal. They keep you stuck at that level. If you need to talk with someone, then first ask that person to listen and not go there. Or better yet, call someone you know won’t go there. It can feel really nice to have someone bolster you up and tell you that you’re better than so-and-so and that you deserved it more. But it doesn’t clear the emotion. You need to be listened to so that you can move beyond the feelings, not so that you can feel vindicated.
