"she's sick of this hell
she's sick of their lies
she's had enough of you
she's said her goodbyes" you repeat She and even sick too many times here.
"if she could be unhappy?
if she could ever be sad?" if she could here
those are just a few areas i believe you could clean up and make this a wonderful peice, it will really grab the reader and be able to keep the flow and attention on the poem better.
i loved the opening of the poem though that was great. if you ever fix this up let me know because i am intrested to see what you can do with this peice!
