CS, love the ambition and as you say its a difficult subject.
I enjoyed listening to it. Especially the 'I cant take it anymore' and love the whistles.
Thoughts only a question about the structure and juxtaposition between sections, I think the one between 1st section needs to be more integrated. The rest are more joined up. On the structure I think I might drop the 1st section and just leave it to the ending. I not sure musically you have to repeat sections, having 4 or 5 specific interlinked elements would work well for me. Then it would be more powerful, imho
Anyway I dont know how you do this is.
