sorry to be so blunt but this piece did nothing for me.
im sure you could have found a better way of expressing yourself that didnt come across as a whinge.
taking the blame for something should be a mature action. it should be something that, while it is hard, is fair and right.
you dont give the reader any indication what it is that is your fault and why it is your fault and why you shoulder the blame.
get some images in here.
give the reader a reason to read this... a point of connection... a vehicle of understanding. right now this is nothing.
who is "you" in this piece and what is your relationship to them?
you dont have to name them or even spell it out but it would be nice if you identified them better and gave them some kind of characteristics to make them more real and viable.
think about adding more punctuation to this piece. it seems lacking right now and while it is not necessary for poetry to contain punctuation to have full effect i think this piece needs more than it has.
i think you could do a lot more with this piece.
