What now?
You could brace for life’s next messy, intricate adventure as it races toward you. But if you can’t countenance that, then retreat—drop off the grid, ignore texts and calls, hide indoors, eat from boxes. If someone does manage to make contact, bore them with details of your mythical back surgery: since the operation you’re walking on a cane, swallowing pain medication with debilitating side effects, and when you’ve fallen you’ve struggled to pull yourself up.
Chances are they’ll not call again.
