This song's strumming pattern is a little hard to explain. I'll try to post a 
backing track to this song, it should make it easier to figure out the pattern.

Verse 1

C                            Am       G    C                
Standing in the midst of a lightning storm listening to the 
Am C
rain,
C                Dm     Em  D7                      Am7
Shock me with a million volts and I won't feel the pain

   Am   C        Em
Desensitized by pain,
  Am  C         Em
Desensitized by pain

Verse 2

Am       C          Am G    C                   
Aim a bullet right at my heart
    C       Am     Em G
And I won't shed a tear,
Dm                          Am Em
Been afraid so much in my life,
        Am    Em    C
That I don't even fear

Verse 3

C                        Em G
Scratch right beneath my skin,
Em           G     D7
Reveal the pain within
Dm                         C  Em
The facades I hold on my face,
        Am       C
Help to take misery's place

Chorus
   
 Am  C        Em
Desensitized by pain
 Am  C         Em
Desensitized by pain
