Let go the past. You cant undo anything. Its done. Forgive others, forgive yourself, learn from your mistakes, learn from others mistakes, remember that NO unkind or thoughtless action ever comes from love but from a place of deep inner pain . You can be compassionate to that pain without condoning the acting out of the pain and release the energetic burden you carry: grudges, resentments, pain, hurt, disappointments, sadness, anger, guilt, let it all go.
