Verse:
Cm                          Gm
I think I'm going through denial,
            Ab              Eb
It's been a while, but it's clear when it hits me.
Cm                          Gm
I think I might have gone insane,
         Ab             Eb
I rot my brain, getting high on our history.

Cm               Gm               Ab                Eb
Always know I'll be the one you'd sink your teeth into.
Cm                Gm                 Ab         Eb
Never thought I'd taste this good to anyone but you.

              Gm        Cm
How you gonna say that, take it all back
Ab                                Eb
Messin' with my head will make my heart attack
         Gm      Cm
And it's so bad, feelin' this sad
Ab                              Eb
Runnin', runnin' circles down a one-way track 'cause
Gm  Cm               Ab  Eb 
Youuuu know what you dooooo

Trapped like rats inside a maze,

It ain't the same, but it sure comes close now.

Pretty venom in my veins
