Brilliant. Absolutely brilliant. I laughed and cried as I read this. You should keep writing, especially since you know to add two spaces after a period. :)
Having lost my son over two decades ago (correction: I didn’t lose him, he DIED), this part early on in your piece rang especially true: “Suddenly the range of the type of sad you can feel, to the type of happy you can feel, is busted open. The spectrum from happy to sad isn’t a foot wide anymore — it’s as far as your arms can stretch and then to the edges of the room and then up the block and over into the next neighborhood.”
I’ve tried to explain that to people over the years, how the heart breaking wide open expanded my capacity for joy, but I love how you expressed it.
Wishing you all you wish for yourself…
