We are all served a little dollop of worthlessness as it provides a contrast to recognize worth. Remember the worth is God given, it is not a function of our achievements, successes or failures, our possessions, our relationships or our looks. The only requirement for claiming self worth is that we are born in this planet. We are worthy enough for this human life, we are worthy to learn the lessons that our sole has put in place for us, we are worthy enough to heal and become whole.  Trusting and surrendering is our ultimate shield.
