Sleeping With Sirens - Stomach Tied In Knots chords

This is just a little bit of the song it is pretty much the same all the way through 
until the chorus when it changes from C to Am to G

           C
Oh, my stomach’s tied in knots
      G                                      Am
I’m afraid of what I’ll find if you want to talk tonight

Oooo Oooo
          C                          G
See the problem isn’t you it’s me I know
                           Am
I can tell, I’ve seen it time after time
                    C   G
And I’ll push you away (oh)
           Am
I get so afraid
            C
I’ll only have myself to blame
