It's embarrassing enough I had to call her for help because I couldn't trust myself to make the step, but to be advised to learn to code while I'm in hospital as I'm leaning on her in nothing but a towel is a new level.
Then again this is the same woman I overheard tell the afternoon guy that I'm "a bit useless" when they switched shifts so I shouldn't be surprised.
It is pretty common for nurses to get ptsd and burn out. Seems like you have found just such a case.
I don't particularly think it's useful to you in the short term but you usually they have pretty thorough exit interviews and feed back collection. Throwing a few buzz words in there like poor stress management might hit some HR computer right.
Then again given the state of the world it just might not be anything to be done in the short term about it.
Probably all the staff that works in the unit is aware of the issue so any cnahcw you get to work around her is a good plan.
