What is the exact identity of these words? Whether it be a song, a poem or whatever, please tell me.?

all I know are these words from that 'unknown'..

'when you miss me i'll be gone. when your world starts to crumble, i'll be so far

away.... so long'.

and a name that goes with it which may or may not have anything to do with it: 'Van Villamor'

and a possible title: 'When You Miss Me'

i tried google and many mp3 sites but is unable to find it, so maybe this isn't a song.

so if the above rings any bell, please tell me. Also include if it is a song, poem, novel etc...

Please and thank you.
