The bottom of everything

I cast myself out to the edge of insanity,
reeling myself in slowly,
waiting for the dark creature below the surface to take notice.
Swallow me, drag me down to a depth with unbearable pressure.
A dark place where every decision,
the slightest twitch is the difference
between life and death.
Describing these moments with you,
dark creature,
is nearly impossible.
I beg to live,
I beg to die.
If I manage to break free,
I only crave to see you again.
