It's my own cheating heart that makes me cry.

I’m feeling so guilty about any old shit
this is it, this is it, this is it, this it
the end was always coming and now its here

so this is the grand finale
the crescendo of demise
this is the happy ending
where the bad guy goes down and dies
this is the end
with me on my knees and wondering why?
cross my heart, hope to die
its my own cheating heart that makes me cry
