~ The middle part, which is certainly prose rather than poetry, is begging to be reworked to fit the rest of the poem. It's where the turn is, where the absolute most important part of the poem is (except for that wonderful third line).

~ You might also consider letting the second to last line go away. "Stupid" just doesn't fit the rest of the vocabulary in the poem. It sounds argumentative and petulant compared to the rest of the pointed, deliberate verbiage.

~ This is totally this reader's opinion, right here. Consider single-spacing some of your lines together, like stanzas. Let them capture complete thoughts—not terribly unlike that middle paragraph, only grouped as lines.
