Very angry and painful poem this is.. You let the reader infact picture every detail. The last lines are what caught my attention.

Then i take a fork to scrape my bone
I scrape and scrape until i fulfill my need
The rhythm of my leaking fluid has now grown
Scraping, digging, painless, yes indeed

I feel the extent of self harm and inner pain in those lines..
Really sorry if yoyr actually feeling this way.
