This is a very strong poem overall and very clear. The tone of sadness is throughout. It seems like here that you used to love a person and they hurt you badly. Or you are talking about yourself here. I love the use of the mirror reflection because when we see ourselves it's hard to see the good. The metaphor is great though. Because though this person did not "kill" you the depressiob you feel is sometimes a lot worse. Overall I loved this poem because it's short but its very powerful. 5/5
