I don't work in health care but I totally relate to your experience dealing with disgusting fat women. As a thin female, it's so draining to work with fat women.  They are constantly plotting to embarrass or discredit you at every chance they get. I have tried to win them over with kindness and even food but they just get nastier.  At my last job I was the only thin woman and the three she hogs were constantly gossiping about me and spreading rumors.  I couldn't take it any longer and left but not before I had lunch with the owner and told him and his wife about the treatment I received and made sure to let those fat asses know what I did.   I am home now taking some time off from working and get to enjoy my days free of their bullshit, but I do regret not standing up for myself.   The problem was though that I couldn't exactly call them out on anything because they would just deny it and defend each other, leaving me to look like the crazy one because I had no one to back me up.  Because I really care and respect the owners, I decided not to take revenge in any other way, but I kind of wish I would have.
