Love the strength in this, so much raw emotion but a real attitude brimming just beneath.
It is very pacey which ties in with the theme of the whole piece.
Your rhyming scheme is excellent, works wonders for this piece and is really natural.
The first stanza is brilliant, you have trimmed the fat away leaving just the powerful words that move the story forward at lightning pace. No flannel just straight to the point and hard.
Love the sarcasm in stanza two, you seem to sympathise yet imediately snap into realization that it is 'so over'
Stanza three is the emergence of real strength of character. This is where you evolve fully into a single minded person.
The final stanza is very fitting, I don't think it could be any more final.
Clever piece.
