"It" happened? What is "it"? I'm not understanding. What did she institute, specifically, that she changed today? (And she hasn't "left"; she's having surgery and will be back in a few weeks unless that changed.) Is it her job to "pick up the pieces"? What would picking up the pieces look like to you? You aren't powerless here. What can YOU do to pick up the pieces for yourself or at least hold them together until she returns from her medical leave? Can you come up with a plan to help yourself?
