F-Am-C
Am-C-G 

F (133211@1)  Am (x02210@1) CWait, (x32010@1)I'm wrong
Am (x02210@1)             C (x32010@1)         G (320003@1)
Should have done better than this
F (133211@1)    Am (x02210@1)     CPlease, (x32010@1)I'll be strong
    Am (x02210@1)       C (x32010@1)     G (320003@1)I'm finding it hard to resist
   F (133211@1)             Am (x02210@1)     CSo (x32010@1)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...
