Compassion comes from love. It means to love, to love deeply, to show mercy, to be tenderly affectionate and to feel for people. Compassion is the nature of children of God but it must be worked out. It's much easier to get even and to revenge when hurt yet the best thing to do during those moments is to be compassionate. You can choose to show mercy to your own self first so that you can be better equipped to do the same to others. Love yourself first so that you can also love others. You cannot give what you don't have. Forgive yourself, treat yourself well and it will be easier for you to reflect the same on others.
