Oh Anika !

I am glad you put your foot down and told her what you thought ! I have "snapped" at people in the past I have worked with. Sometimes it is just needed.

Please try to not feel bad for your actions ,,, YOU did nothing wrong. Isnt this girl that told you the first or second day that she worked there before and got into a physical altercation with a coworker?

I am sorry that you have been dealing with her and her nonsense. Be proud that you stood up for yourself and your coworkers..
