It might be a good idea to continue this theme of melancholy? I'd be interested to hear what you have to say about it. This seems more like a fragment to me. Personally the whole 'cutting' phenomena seems very bizarre to me, but maybe feeling something is at the root of it.
Why do people always seem to complain, or alude to the idea that something is wrong with it, if a poem is short? If the emotion is poured into twenty stanzas, or two, or even one, what difference does this make? Haiku is short, yet I never hear anmyone complaining about that. Anyway, I loved this poem. It represented the angst that I think many people feel, so it is easily relatable. Nice write!
I found myself a bit confused by the use of "bile". I assumed that it had some significance, thinking that you'd have used "fluid". I was hung up on why you used the term because I was thinking of bile as the fluid produced by the pancreas. Then I looked it up and I saw that bile was also used as a synonym for "hate". That was a moment of dawning.
I understud much more clearly then and it made sense and resonated with me.
I like the imagery. Bile in place of blood evokes a much more creative image. It's... short of course, but that's a given. Let this be my first review that is longer than the piece I am reviewing.
