A heart.

What do you call a sponge

That never wrings out

A mind so full

No thoughts come out

These emotions flow

Endless and continuous

The flow is so thick

It's all just darkness

A cavern of loathing

Too deep to control

Space so vast

Just an empty soul

How possible this is

Full where nothing exists

A hollow husk

With useless organs

I cry inside

Where smiles usually lie

I tear apart the seams

In places I used to dream

The sadness seems unreal

Reality can be cruel
