A quote from one of my father's sermons:
    The reality of grief is the solitude of pain, the feeling that your heart is in pieces, your mind's a blank, that "there is no joy the world can give like that it takes away." (Lord Byron).
No child should predecease a parent, let alone a grand-parent.
When you mourn him least, you'll remember him best. It will come, I promise.
Godspeed.
