When you are joyous, look deep into your heart and you shall find it is only that which has given you sorrow that is giving you joy. When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight. Khalil Gibran
Joy and sorrow are the same. Both are there for you, to teach you, to enrich your soul. Embrace the suffering for once you do, you can move past and learn the lesson. Then you can experience the love that was always there.
