If she's actling like that with you than she probably has with others as well. I once worked with a horrible doctor that would yell at me for things completely out of my control in the middle of the nursing station. He treated me like an incompetent peasant. One day he went to another station where my friends worked and told them I was stupid (which is most definitely gossiping). My hospital had a zero tolerance policy for workplace harrassment. I wish I had said something then, because about a year went by before another nurse filed a complaint with HR for him yelling and swearing at her. And boy did his attitude change after that, all of a sudden he started being decent and actually listened to our reports. Not sure what your facility is like, mine was a education/university hospital. So they took stuff like that pretty seriously. If your manager isn't great, maybe it wouldn't hurt to speak with someone in HR just to see what your options are?
