Cannonball Chords

I don't know the whole song but I sat down and just kinda figured out the chorus.

Let me know if you have corrections. I don't think the Am's right but I can't figure out 
should be there.
Thanks:).

[CHORUS]

C                                  G
Cause you save me baby, from myself

         Em     D                  C
Can I be saved, Only time will tell.

           C                            G
You're the difference, between luck and love

                     D                          C
Hit me when I wasn't lookin at all, love like a cannonball.

Am                   C
Tear down the wall, love like a cannonball.
