First, i really like this. Second, I haven't commented in a long while so my comments or suggestions may be shit.
What I like"
Love the descriptions, especially "penny slits"
My suggestions:
It reads a bit too wordy, almost like a monologue and not a poem to me. I say eliminate ruthlessly any words that do not add value and take another peak at it. I bet your decriptive, to the point words will have even more strength.

I agree with Shan about the write being too wordy, though it didn't read like a monologue. It just feels like it needs to be trimmed up. Also, maybe separate the last two lines. Those lines, I think, should stand on their own, alone.
The way your first two lines play subtly throughout the write is very well done. At first I wanted a better transition, but then it speaks for itself. Because there is a quietness in grief, even when anger, bitterness and fear are harbored. It's a matter of coping and coping with coping. I especially liked the bit about the fingernails, because I remember thinking that. I remember being so troubled by that.
Great write.
