This is quite a sweet poem or maybe song... the question mark on the "lyrics" confuses me... i don't quite understand if you did write it as a song and then thought it more as a poem or wrote a poem that looked then like a song...
anyway... poem or song, it is amazingly meaningful... :)

my fav part would be:

"I'll wait for you.
So hold up my letters.
What's left to be said?
Are they just reminders
of what's still ahead?
And if life is spent waiting for that next tomorrow...
Please promise that you'll still be here.
I'll wait for you."

i ask myself how would it sound like, as a song... what melody would fit in... =) lol you made me daydream :)
wonderfully written
*keep on*
