Good to see you've made use of FP's new formatting. It's very appropriate how you bolded most of the dies, deaths etc. Makes it more powerful. A very well written piece. Perhaps if you want to make it stronger try altering this line "But I know all the real truths." You are right simplicity is bliss (double meaning, but here I'm using it to be helpful :P). Shorten it, and make it stand out more. It's up to you but something like 'But I know the truth.' - It's short, sharp and conveys much more bitterness than your original line.
-Keep writing

Some very good lines in this poem and interesting how you put the word 'death' and its other associate 'die' in bold. The narrator, however, seems to lack a solid background, so the message in your poem is a little scattered...
