Goodbye Heart (A tribute to Mahoromatic)

I wrote a metal duet a few years ago.

My days were numbered
I knew this when I came to you
My end draws closer
With every moment spent with you

Goodbye (Goodbye)
Goodbye (Goodbye)
Goodbye heart tonight
Goodbye (Goodbye)
Goodbye (Goodbye)
It's time to start the fight
You know I'd like to stay another day
But time's up over already
So goodbye (Goodbye)
Goodbye (Goodbye)

There's something I should tell you but
I'm terrified of what you'd think
Something so devastating
I don't want to see your heart sink

So
Goodbye (Goodbye)
Goodbye (Goodbye)
Goodbye heart tonight
Goodbye (Goodbye)
Goodbye (Goodbye)
It's time to start the fight
You know I'd like to stay another day
But time's up over already
So goodbye (Goodbye)
Goodbye
(Goodbye heart)

(I'd rather step on a nail)
(Or be impaled than have to face this world without you)
You have to move on!
(There is nothing so painful as the pain I felt)
(When I saw that mushroom to my knees I knelt)
(Now I have to live)
(I have to live)
(Without you)
(AHHHHHHH!)

(So)
(Goodbye)
(Goodbye)
(Goodbye heart tonight)
(Goodbye)
(Goodbye)
(It's time to end this fight!)
(You know I'd like to stay another day)
(But times up over already)
(So goodbye)
(Goodbye)
(Goodbye)
(Goodbye heart!)
