Really good poem, had good rhyming that didnt seem forced to me.... The only thing i would suggest is changing the word zombie from this line

"What's the reason to exist,
When your gone and never truly missed,
Another day inside this place,
Left with a zombie of a face"

I feel you could have fond a better word that would have a better effect and really tie off the poem

Yeah it was something I just put together really fast without really thinking about it
