May your grandmother run free with the winds now, and may your grandfather and your family find comfort in healing and comfort in friends. And to you, I send a hug for the sorrows you go through.
These words from Kahlil Gibran comforted me a lot when a friend of mine died suddenly. Perhaps they might do the same for you and your family, to ease the grief.
"Your pain is the breaking of the shell that encloses your understanding;
Even as the stone of the fruit must break, that its heart may stand in the sun, so must you know pain.
And could you keep your heart in wonder at the daily miracles in your life, your pain would not seem less wondrous than your joy,
And you would accept the seasons of your heart, even as you always accepted the seasons that pass over your fields,
And you would watch, with serenity, through the winters of your grief"
