I like your use of punctuation in this. The end really hits hard. I do agree with Marie Ellen that "where I'm at" jolts the reader somewhat, but do whatever speaks to you.

It took me a couple reads to start getting the feel for this, but I really liked it. Especially how the entire thing is a "collision," and we're brought right into that metaphor from the very first word. You carry it through flawlessly. I would suggest "you're never where I am" rather than "you're never where I'm at." Technically, you should never end a sentence with "at." And it sounds superfluous when "where I am" means the same thing.

This was really great! "another shattered self lying in the glass: a snapshot, frame long-lost" were my favorite lines.

Thanks for the review!
