Wow, that was really sad
I don't understand how exactly that could be classed under dark, but since you are the author you do have some liberty to put it under whichever genre you wish. But that is not the point of the comment...
This poem of yours... it was awesome i loved it and the title is just awesome. I saw the title and I thought it would be about something else, I never expected what I read but the poem was great. Really well done...
Good job
