Beautiful rewrite. I really like how you tied the snake in. At first I didn't get it, but then yes, I did! (The way you hold the pen in your hand, as you hover, poised, hesitant with thought, before your hand strikes the page in mad fever and devours the page in script. Very moving.)
I love the rhythm of this bit of the poem:
I'd be stopped in a lollipop,
However, I will say, it doesn't really flow with the rest of the poem to me. The rest of the poem is so eloquent, dare I say, fancy. But the image of a lollipop is so casual. Not sure if the phrasing can be reworked keeping the "I'd be stopped in a lollipop" which I think is visual enough to understand the metaphor between pen/lollipop (but somehow get rid of the "with my pen as the stick!"
Just my 2 cents. Very creative piece. And relatable.
