As hard as it is, do not take it personally. Especially since she is doing this to the aides and other nurses (means that you are not alone in this). I would document her behavior, tell the powers that be and ask them how they think this should be handled.

Well, it doesn't sound like it's personal.

YOu won't reason with her and she isn't going to get better.
You cannot reason with a person who is not rational and when you can look at what you're doing as a job and not expecting results like that book "How to win Friends and Influence People" you will be more at peace.

This is a person with mental illness and the sickness will only get worse. It has nothing to do with you. The bad news is, it is something you will have to put up with.
