I don't normally go for angsty stuff, but I rather liked this.
It's simple and direct, and manages to convey the speaker's desperation without going on and on about how the world is so hard and uncaring.
My only problems are minor ones and they relate to the last three lines of the second stanza.
I may be wrong, but the way it seems to work best for me, is with a hard stop at the end of line 5, "That's carefully placed", and requires perhaps, a pause before moving on to the last two lines.
Line five to me, describes the mask, but lines 6 and 7 feel like they describe the speaker.
I'm not sure if that's how you intended it, but if you did, it might work better if there was some way to make the transition of desriptives definitive.
The only other thing that seems somehow incongruent is the use of the word "crashes", and for me, the general feeling of fatal finality would be better served by using something more "passive" such as crumbles, crumples, slides,
This is a quiet and defeated passing, not an act of defiance.
LOL...this is of course all strictly my opinion.
