I need help finding a song...

My brothercan only remember a few lyrics and now my mind has gone blank on the song, and I know I have heard it to...
I (I) will not (will not) wait for you
sounds like they are repeating the words I and Will not... and it's almost their yelling...... I thought linkin park song or three days grace song but can't find anything....
If anyone knows the song please help me... This it driving me nuts trying to find it... I know I have it saved to my computer.. least I think I do, but that would take forever to find it!
