This has so much potential.
The first three lines are really good but the last word seems shoehorned in for rhyming expediency which is a real shame.
I'd rather see the last word really make me go Wow! than perfect rhymes that leave the reader deflated.
What was it that you were trying to convey in line 4?
How about "Broken with pain... " (play on the words 'broken' and 'pain/pane')
