I found this on Pebbledash's blog and I hope she doesn't mind me using it here. I found the last 2 lines particularly moving.
A Pueblo Indian Prayer
Hold on to what is good,Even if it's a handful of earth.
Hold on to what you believe,
Even if it's a tree that stands by itself.
Hold on to what you must do,
Even if it's a long way from here.
Hold on to your life,
Even if it's easier to let go.
Hold on to my hand,
Even if I've gone away from you.
