I wrote one similar to this several years ago, "I Wish", when I was frustrated with my boss ... it's always good to release. :) Well done, Eileen, nice reading you again!
I like it and love the idea that the mind could do this so easily, when my daughter got married she wrote her maiden name on a white helium balloon and holding my hand she let it go into the night to symbolize her becoming the wife to her husband although she assured me I would always be her star.
Breathe it out!!! I think it might help at least. But I don't know if it turns black. You may a tinge of multiple other hues mixed into the darkness. The trick is to keep that powerful balloon from floating away with you! :-
