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.
Every workplace seems to have that one psycho. Sorry you are dealing with this. Remember all the other nurses who are decent and kind and take their attitude to heart and not hers. The others almost certainly hate her guts anyway.
