In essence, our friends are the life-affirming fountain from which we drink. Good friends fill us up with warmth, honesty and a sense of well-being. If you feel drained, empty, belittled and insulted by a friend you should acknowledge that this is diminishing your life experience and not enhancing it. In this case, I would move away from this person, honor whatever good you did get from them in the past, and move toward those friends in life that only want to help light your way!
