My mom died

My mom died suddenly after a very traumatic 24 hours in the ER and ICU. It happened on Monday and completely knocked me on my ass and swept me out to sea. Monday night in the hospital, I texted my director and assistent director that there had been an accident and it was likely my mother’s end of life and I would need the rest if the week off at least. Well, my assistant director responded by asking me if I had found a sub yet. I was completely shocked. Has stress clouded our conpssion entirely? There is no decency. My mom died the next day and my whole body is wrecked from this experience. I’m supposed to go back to work on Monday and the thought of seeing her in person makes cry. I want to tell her how inappropriate and insensitive that was. Would you say something? How would you say it
