And its name is...

A melancholy permanence
Is set within my mind
Draining all my knowledge
Evading suicide by time

Sky's the limit
I often hear them say
Unfettered by distinctions
Between dimensions of time and space

Secret greed hides success
Where boundless truth is a lie
Testing the absolute outer limits
Of how much I can endure this time

Criticized, sanitized, institutionalized
An end to your pursuit
Handed off for someone else
To arrange the burial suit

No one wants to dirty their hands
With the undeniable scent of demise
You can't outwit, outrun, or hide
Though til your last breath you try

It lingers in the shadows
The constant without shame
It touches us all and brings an end
And death is its given name
