Something about Gratitude

Lately, I've been thinking a lot about gratitude. Between my time of need (the surgery) and a friend in need (issues with her baby's health,) I am forced to feel a gratitude for my life far deeper than can be expressed with words. I try to pray my thanks and write my thanks, but it is not enough. Is it greedy to long for the words, the ability to express myself adequately? I am left shaken in blender of grief for those who are grieving and gratitude for the life that is mine.
