F-Am-C
Am-C-G 

F    Am   C
Wait, I?m wrong
Am               C           G  
Should have done better than this
F      Am       C
Please, I?ll be strong
    Am         C       G 
I?m finding it hard to resist
   F               Am       C
So show me what I?m looking for

And that's basically it throughout the whole song(:

Sorry I couldn't get the other two chords after the last C...
