"Your the reason I hide,
and your the reason I cry,
your the reason I hurt,
your the reason I lie,"

All of those 'your's should be you're
~~~
"and shattered it in to pieces,"
in this case, 'into' is one word
~~~
"leaving it to be mended,
leaving me to cry,"
I liked the repitition here, and throughout the poem. The repeated words added a great emphasis and helped develop a certain rhythm. I thought this poem held a lot of emotion and developed it pretty well.
