You might be thinking of another Linkin Park song, "Numb". Looking at the lyrics, it has a few lines very close to the ones you remembered from it (emphasis mine), but it's missing "something I am not gonna say to you" and "I love you".
Put under the pressure of walking in your shoes
And every second I waste is more than I can take
And obviously, the gruff voice that sounds like the one in "In The End" would be the same guy. :)
