I give you all my condolences for those who have lost family. but always remember this isn't the last time you shall see them, and they will always remain in your heart. I have always found poetry to be a great way to express things. so here is something off the top of my head.
what is lost will be found
pain's ties are unbound
do not fret they are free
for them you should be happy
one day you will meet again
when it is time to meet your end
i remeber what it was like to loose someone and well this is what i felt.
and you are in my prayers.
