Plum out of luck in a bird's eye

As quickly as my brain can perceive, it is gone.
Extinguished the unavailable.
These steps don’t progress anywhere,
Where to fear, no where but here.
The cavities wrapped in skin are plugged with corks,
I’ve seen there are too many fish in the sea.
One by one, we aren’t content to be
Purchased the answers in a hard cover,
I never will understand the expenses of life.
Called for duty, called for vote,
But what is it called when my best interest can’t float
It’s almost like drowning ten feet above the ground
I pity the birds with their encompassing view.
