A need is only worth so much

A need is only worth so much;
It has a value one must touch.
And, finding one's not worth the cost
In severed lines, in maelstroms lost,
Needs make one recognize his crutch.

The poison flowing from the ducts,
The poison bleeding from the cuts,
Is liable to get you tossed.
The price is steep, and one is weak.

If ever found in quicksand sucked
Beneath insanity or clutched
By helplessness, the hidden frost
Will choke you first; when dread exhausts
The one who never sought it such,
My price is steep and I am weak.
