Credit for the 'difference between sanity and madness' line goes to Alan Moore, I just borrowed it:

 

A burning sky lights the cry,

as the world looks on.

They see the pain, the maddened stare;

they walk on and do not care.

 

I scream for them as much as me,

I scream for them because they can’t see,

that ‘the difference between sanity,

and madness

is one bad day’.

 

A silent shout fills my mind

an echo of things left behind

a prelude for what is to come

a requiem for things I should have done.

 

I hold my head and scream,

I close my eyes and cry,

clench my fists by my face,

dissolve into a tired sigh.

 

Tomorrow, it all starts again…
