It is fascinating how often we crave the acceptance and approval of those who won't accept us. It is an unhealthy pattern to continually pursue people who reject us. We do this because we see our lovability as directly related to their approval so we keep trying to be "better" or "do more." We do this so we can approve of ourselves through another person's approval of us, as if their approval finally makes us good enough.
The healthiest way out of this pattern is to look at why we deeply believe we need the acceptance of those people. Do they determine our worth? Should we have to prove ourselves all the time only to hear we are not measuring up? If so, we are not picking the right people to have relationships with. The greatest gift people who don't approve of us give us is a more defined idea of who we are and who we choose to be. We make the internal agreement to never let another oppress us and keep us down.
