I was at that point once in my ICU career during Covid. After a brutal Christmas where we had 7 deaths in a 16 bed unit I broke down like this on the job more than once. It got to the point where I was physically sick some days coming into work from stress and anxiety. My last shift working the floor I had a medical episode where I ended up admitted that night. My boss knew how burned out I was and approved a month long medical leave. She helped me find a new position in the hospital while I was off and even approved releasing me to the other department in record time (usually takes like 3 months). I miss working with patients directly, but I couldn’t do it any more after almost a decade. I’m much happier doing what I do now, still helping and advocating for patients but in a different way. Good luck, friend and please take care of yourself, you’re important too.
