A melody, a memory, or just one picture

I see my vision burn, I feel my memories fade with time
I'd do anything for a smile, holding you 'til our time is done
We both know the day will come,
but I don't want to leave you
Seize the day or die regretting the time you lost

So, what if I never hold you, or kiss your lips again?
So I never want to leave you and the memories for us to see
I beg don't leave me.
