Katy Perry - Part Of Me chords

Hi! This is the first verse. The chord progression is constant.

Dm                     F                    Bb   C
Days like this I want to drive away

Dm                          F                          Bb
Pack my bags and watch your shadow fade

                   C    Dm                   F
You chewed me up and spit me out

                Bb
Like I was poison in your mouth

  C    Dm
I fell deep

                  F
You let me drown

                    Bb
But that was then and this is now

                C
Now look at me!
