Intro:

F A Bb C

F A Bb C

F                      A                  Bb          C
I thought Id write, I thought Id let you know
F                                      A              Bb       C
In the year since youve been gone Ive finally let you go
F                         A               Bb         C       
And I hope you find some time to drop a note
           Am
But if you wont
         C
Then you wont
F         A     Bb    C            F             
And I --------- will consider you gone


F                      A                  Bb     C
I know that you went straight to someone else
F                               A              Bb      C
While I worked through all this shit here by myself
F                            A                Bb     C
And I think that you should spend some time alone
           Am
But if you wont
         C
Then you wont
F         A     Bb    C            F             
And I --------- will consider you gone


-Bridge-

Dm G G7 G Bbm F Bb Bbm

        F          Dm
I wake up in the night
       Bb      C
All alone and its alright
       Dm                 G
The chemicals are wearing off
             Bb        C#maj7
Since youre gone       

F                    A                Bb     C
The days go on, the lights go off and on
F                    A                 Bb      C
And nothing really matters when youre gone
F                     A               Bb     C
If you think that you feel nothing at all
         Am
If you dont (if you dont)
          C
Then you dont (no, you wont)
        Am
If you wont
         A
Then you wont
F      A     Bb     C
And I -------- will
F       A    Bb     C
Then I ------- will
F            A      B   C              Dm   Bbm  C#maj7  F
Yeah, and I -------- will consider you gone
