 scratches. Just listen to the song or the youtube video to find the exact
 timing and rhythm for it.)
Verse 1:
(Play the intro riff over the first verse. It'll take a while to be able
   to sing and play along with, but it can be done.)
You are the cancer spreading its wings
 So selfishly unaware to the things
 Resistance is fuel into my well-being
 I feel my heart leaking
Verse 2:
C#5 F5 C#5 C              F#m     C  Ebm          C              
           You start as a fissure, a crack in the skin
C#5 F5 C#5 C             F#m C Ebm   C
           You become an ulcer permeating
C#5 F5 C#5 C        F#m C  Ebm  C
           If I had known about you to
C#5 F5 C#5 C           F#m  C     Ebm     C
           Would it be soon, what I do to you?
Pre-chorus:
A5                                 
 I don't want to hate you, but how could I not?
B5                      C5
  You killed off so much  I held dear in my heart

Verse 3:
C#5 F5 C#5 C             F#m  C    Ebm     C
           It's getting harder and harder to breathe
C#5 F5 C#5 C                   F#m   C    Ebm     C
           Choking on the same air as the walking disease
C#5 F5 C#5 C           F#m   C      Ebm    C
           You are the thing that's killing me
C#5 F5 C#5 C                   F#m  C  Ebm  C
           From the inside out, let me be
