To be rejected by someone doesnt mean you should also reject yourself or that you should think of yourself as a lesser person. It doesnt mean that nobody will ever love you anymore. Remember that only ONE person has rejected you at the moment and it only hurt so much because to you that persons opinion symbolized the opinion of the whole world of God.
Love they say enslaves and passion is a demon and many have been lost for love. I know this is true but I know too that without love we grope the tunnels of our lives and never see the sun.
