I struggle with this every day. I think it's the price you pay for having a certain degree of intelligence and self-awareness! I read the following verses from the Rubyiat at my Mum's funeral last year -she did love a drink! They sum up the approach I try very hard not always very successfully to adopt - we are here for such a short time and are in all honesty quite insignificant in the scheme of things. But a life enjoyed and well-lived is the only sane response to our own ephemerality.
You know how little time we have to stay,
And once departed, may return no more.
Ah, my Beloved, fill the Cup that clears
Today of past Regrets and future fears.
Ah, make the most of what we yet may spend,
Before we too into the Dust descend;
Dust unto Dust, and under Dust, to lie,
Sans Wine, Sans Song, sans Singer and sans End!
The Moving Finger writes; and, having writ,
Moves on: not all your Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all your Tears wash out a Word of it.
When You and I behind the Veil are past,
Oh but a long long while the World shall last
But the world of our Coming and Departure heeds
As much as the Ocean of a pebble-cast.
Ah, with the Grape my fading Life provide,
And wash my Body whence the Life has died,
And in a Winding-sheet of Vine-leaf wrapt,
So bury me by some sweet Garden-side.
