It rhymes very very well. It clearly explains the process of one who is in deep emotions filled with anger, sadness, regret and a few other things. It seems to follow a clear path in terms of ideas and the message is interesting.
I personally think this as one of my favorite poems of your repertoire of yours that I can remember of. It seems mature and well thought out. I have difficulty to find a fault in it, which is a good thing XD
