The song pretty much follows this pattern throughout the whole song:

F, Dm, Am, C

I'll give you the starting lines...

       F                                 Dm
And tonight I lack the strength to even move..

      Am                    C
You walked, and watched me die..

       F                      Dm
But I know this is harder for you...

     Am               C
For love has let you down..

CHORUS:

             F     Dm
And I can't feel you...

          Am               C
I'm not alright, I'm not alright...

Again, follow that pattern for the whole song and you should be good to go!

If you want the melodic parts, I've tabbed them for you as well. i'm not gonna tab all 
counts, but this is basically it.
