Pretty much the whole song is palm muted (P=Palm mute)
The strumming pattern is like this:
e--------------------------------------------------------------- | 
B------------8-----------8-----------4-----------4-------------- |

D------------8-----------8-----------5-----------5-------------- | 
A----0-6-6-6-6---0-6-6-6-6---0-3-3-3-3---0-3-3-3-3-------------- |

Its been so long

Since I've been alone
C5
I cant think of a time when you
Eb5
Weren't right
                     C5
Here breathing by my side
Eb5
My mother said

To talk things through
C5
Don't let heavy hearts pile up on you
Eb5
But how can I
                        C5
When I'm too scared to speak
A#5          C5
I cried all night
G#5               G5                   Fm(2)
But I put in too much to turn away now

Eb5 C5 Eb5 C5

Eb5
I've been waiting for you to say
C5
That I'm better off

Without you
E5
Anyways
                                    C5
But we both know that that's just a lie
A#5                     C5
But what's said is done
G#5           G5
We're almost gone
                 F5 (no more palm mute)
I can't see your face
   C5      G5
Woooahhh woooah
                   F5
I cant find my way
   C5      G5  
Woooahhh woooah
                     F5
I cant catch a break
   C5      G5
Woooahhh woooah
                      F5
I cant count the days
   C5      G5
Woooahhh woooah
                        F5
Everyone looks the same
   C5      G5
Woooahhh woooah
                        F5
Everyone looks the same
   C5      G5  
Woooahhh woooah

Etc., etc., etc.
