I know you want criticism on most of your poems, but as a rule I don't really critique poems that are emotional and personal, because who gives a damn about rhyme and rhythm and poetic devices and symbolism when your friend is hurt. All I can say is I thought the rhyming was fairly natural, and that the rhythm was pretty consistent, and that the lack of poetic devices is understandable because this poem is a "talking" poem, as if you are addressing someone directly.

wow! sad, but good!
wish you the best!
