Laurell K. Hamilton said this quote

You can not die of grief, though it feels as if you can. A heart does not actually break, though sometimes your chest aches as if it is breaking. Grief dims with time. It is the way of things. There comes a day when you smile again, and you feel like a traitor. How dare I feel happy. How dare I be glad in a world where my father is no more. And then you cry fresh tears, because you do not miss him as much as you once did, and giving up your grief is another kind of death.
