My Unholy Sin

Sometimes I hear my heartbeat
Pounding in my ears
Are all my decisions really concrete?
We lift another shot, cheers!
Goodbye to my furrowed eyebrow
And my frown disguised as a grin
Let me take one more shot now
While committing my unholy sin
I think about all I've done wrong
My friends sing their drunk song
While I think about all the horrible thoughts
Left in my heart and brain to rot
This is supposed to be my happy hour
But now my tears are giving me a shower
