I haven't found correct chords for this song so I thought I'd figure them out for myself.
 I haven't been playing the guitar for more than a month so these chords are probably very basic.
 I hope you find them to be helpful anyway.  


Verse 1:

Em          C
I tried to kill the pai-ain

Am              D
but only brought more.

Em      
I lay dying.

C      
And I'm pouring

Am              D
Crimson regret and betrayal

Pre-Chorus:

Em            C         Am          D
I'm Dying Prayi-i-ing Bleeding and screami-i-ing

Em                 C
Am I too lost to be saved

Am         D
Am I too Lo-ost

Chorus:

Em              C        
My God my tourniquet

Am                D 
Return to me salvation

Em              C
My God my tourniquet

Am                D
Return to me salvatio-on


Verse 2:

Em          C
Do you remember me-e

Am             D
lost for so lo-ong

Em      
will you be

C                  Am
on the other side

                       D
or will you forget me-e

Pre-Chorus:

Em            C               Am          D
I'm Dying Prayi-i-ing Bleeding and screami-i-ing

Em                 C
Am I too lost to be saved

Am         D
Am I too Lo-ost

Chorus:

Em              C        
My God my tourniquet

Am                D 
Return to me salvation

Em              C
My God my tourniquet

Am                D
Return to me salvatio-on


Bridge:

Em              C
My wounds cry for the grave

Am                       D
and my soul cries for deliverance

Em         Am
will i be denied

C          Am         D      
Christ,  tourniquet my suicide



E C Am D (til the end)
