I like it, but I think it needs more description like is this person in love or are they just really good friends that have spilt up? if they are in love explain why or try and give us an indication of how it has affected that person.
the best example of this is the first few lines of the origin of love.
Love is a drug and you are my cigarette
Love is addiction and you are my Nicorette
Love is a drug, like chocolate, like cigarettes
I feel sick got to medicate myself.
this explains that this person is missing or loves another person terribly that they are craving for them.
