Lack

[Leah S.]

I am not a poet.
I lack the substance upon which to write. Usually that's paper.
I do not carry a messenger bag,
brimmed with spontaneity and colors. Do you think 'brimming' would fit the tense better? "Brimmed" should have "that" in front of it.
However, i dare not let my arm rest, for it will
crush what i lack. I didn't get this until I read the following sentence.
Under my arm hangs an absence,
a lack of substance. These two lines are the best lines, but they would fit much better if they appeared before the preceding two lines. That would also allow you to get rid of "However."

I pull file folders
with no labels and no contents
and pull out of a bag that has no bottom,
bottomless. Syntax be all messed up. I believe you could fix it by eliminating "and pull" altogether in L3. Unless you really did mean that you were pulling the bottomless out.
Why should it have a bottom
with nothing to fall to it?
The grey file folders
have no rectitude ,no vice.
They leave me
in the same position they were pulled from:
bottomless. Wait.....what? Bottomless is not a position, it is a condition.
They leave, leaving nothing to speak about, How do those grey file folders perambulate? In trying to figure that out, I had a flashback to Mickey as the Sorcerer's Apprentice.
but much to be spoken. My conclusion is that there is no valid subject for this poem, but the narrator insists on maniacally gabbling anyway.

Sorry, but I think you should start over. Carry on, Leah
