This is just a very simple way of playing the song.
I'm not positive about the pre-chorus or bridge.

Intro/Chorus:
She's not it...
          F (133211@1)   C (x32010@1)   G (320003@1)   C (x32010@1)   (x4)


Verse:
You know I'm glad that she's not alive...
F (133211@1)          C (x32010@1)       G (320003@1)       C (x32010@1)     (X 4)

Pre-Chorus:
But you know me, I will do what I gotta do, in spite of you...
             Am (x02210@1)       C (x32010@1)             F (133211@1)          Dm (xx0231@1)  (x2)

...Miserably
   F (133211@1)CHORUS:
(See Intro)

2nd verse (Same as first)

Bridge:
Cause I'm leaving
          AmI'm (x02210@1)Leaving
    CAnd (x32010@1)I just can't help these
      FJust (133211@1)can't help these feelings
                      GI'm (320003@1)still breathing
          AmNo (x02210@1)more deceiving 
          CAnd (x32010@1)I just can't help these
      FJust (133211@1)can't help these feelings
                      Dm (xx0231@1)CHORUS (x2)


Enjoy.
