The opening line was incredible, it totally pulled me in and the word choice here was definitely powerful. Nicely done for such a simple write, you're really captured not only your emotions but something so overwhelming on the page.
I am in lack of words to describe the beauty I see in this writing so I'll keep my words short just like your short and crisp poem.
In very few words you gained the attention of your reader and delivered your thought and message precisely. Your description of emotions as mobile and undependable and following it, your usage of perfect similes is remarkable. An extremely beautiful write.
