This is how I play it. Based on Billy Howerdel's demo version.

You can easily transpose this to be played like Am, C, F, G instead.

Em G  C    D   Em G    C    D
Metaphor for a missing moment

Em   G  C     D    Em  G   C   D
Pull me in to your perfect circle

Em   G  C       D  Em    G     C    D 
One womb, One shame, One resolve

    Em    G    C    D    Em   G   C
Liberate this will to release us all

D   Em        G          C
Gotta cut away, clear away, snip away and sever this
Dm        G     C
   Umbilical residue, keeping me from killing you

Em G C

D         Em       G           C   D
And from pulling you down with me here,

Em G C

D     Em       G   C    D
I can almost hear you scream

Em F

        Em           G               C
Give me one more medicated peaceful moment
        Em           G               C
Give me one more medicated peaceful moment

       Em                   G            C
And I don't wanna feel this overwhelming hostility
       Em                   G            C
And I don't wanna feel this overwhelming hostility

Gotta cut away, clear away
Snip away and sever this
Umbilical residue

Gotta cut away, clear away
Snip away and sever this
Umbilical residue,
Keeping me from killing you

Snip away and sever this

C                       Em
Keeping me from killing you
