im having trouble writing a poem for class

 I smashed a beer bottle against a rock
And to my surprise I now have a large
Gash in the middle of my palm. It was
Skunked, the type of beer I would hide
In the back of my dresser behind my
Socks (just like my mom does with her
Cigarettes) to crack open on an evening
Where I feel a bout of perturbation about
To enter. The blood from my hand spilt
Onto my sweater, the one I wore to my
High school graduation and great uncles
Funeral.
