Where the world is the zero?

When did all desaturate?
Melancholy become more grey?
Zero zero where are you?

When did all come crashing down?
Not even make the slightest sound?
Zero zero what did you do?

Zero zero where'd you go?
Zero what did you do?

Why'd you pack your stuff and leave?
Not say one word, even to me?
Zero, i've earned more than this

Zero zero where's you go?
Zero what did you do?

Please bring back the anger
Some kind of rage
Bring back the sorrow
Bring back anything
Bring me back my heartache
I'd love to hurt again
Because feeling less than nothing
Is worse than crying
