Tantalus is a figure from Greek mythology, who stole the nectar of the gods to take back to earth. He was punished in the afterlife, on a beautiful island with fruitful trees and clear water, however when he tried to drink from the sea, or eat the fruit, they receded. He was stuck, starving in purgatory. (He also cut up his son and tried to feed him to the gods, what a mistake.)

Tantalus

How many times have you said that this, this is the last time,

Like Tantalus watching the sea recede before your fingers,

Your resolve washes away, goals just out of reach

How many times have you dredged up the determination,

Only to watch it run through your fingers like sand,

The lies you tell yourself at night turn into lullabies,

They evaporate into the darkness,

Never to be seen in the light that pools behind your curtains,

How many times can you say I hate you, I hate you, I hate you.

Hold the hurt to your chest and breathe it in,

Take a drag on disappointment,

When your stomach, and lungs, and heart say no,

Take a knife and carve your chest in half,

Let your guts empty onto the keyboard in front of you,

Bleed words from your fingertips.

Make your pain public,

And fuck everyone else.
