Your grief will find a place in your life with the passing years, but will never go away. There is pain and emptiness right now, but that will ease as you begin to absorb the loss of your loved one. Have you ever thought of your grief is an expression of your love? Why else would you feel the way you do?
If someone tells you that you should be through grieving, it is the same as telling you that you should be through loving. They do not understand that your grief is an expression of your love. When in doubt, listen to your heart.
