Then go and talk to her and tell her how you feel then if doesn'y aknowledge how feel then go go striaght to her supervisor if that doesn't work then just tel her to %#@&#! off cause that no way to be treated at work or at school, the best thing to do is just confront her and tell how you feel, it might not be easy but it will work and if she doesn't listen then you weren't meant to work there.
