I posted a shorter version of this to my Instagram feed, but thought I'd share it here for easy reference and reminder...
I called in sick the other day.
Last Wednesday, a colleague asked me if I was feeling alright because I looked like crap (I have rather blunt colleagues). I should have taken her concern to heart and asked myself if I really was alright, but I laughed it off and told her I was just fine.
But actually, I wasn't.
