Metaphoric Coffin

I'm inside this coffin

Made of sparkling glass

I pound and pound

and fissures form

with strings of colorful cracks

This one's crimson

These are black

And here

one forms a noose

But outside, some people lurk

Ignorant of my pain

I scream until my throat goes dry

I scream until it bleeds

I whimper

cough

and pound some more

New cracks are in the glass

More black

Some blue

The noose falls from the "sky"

I cry and beg for them to see

It's hopeless at it's best

There's no knight in shining armor

Do I do it

do I not

How do I make them notice

If they can't help

then what's the point

How do I save myself?
