I really like this because for one I relate. For two, it kind of goes a bit chaotic when you finally "break through (your) paralyzes." and it really adds an urgency and sense of liberation to the piece. At the end you said it scares you right to your senses and I think that the poem, in my own perception and mental voice, It goes from a sense of constraint in the beginning to the urgent, out of control feeling, to a sudden stop. A deafening quiet that is in no way peaceful and is instead a wary and fearful silence.
I don't know, maybe I'm completely off base here. I just wanna say it was very nicely penned. :)
