Wow. Sounds like this woman is really unprofessional. It really is crappy that after so many years in a job that you were comfortable with, and people you liked, this person has to come along and ruin it I don't understand her motive, but I never do with people who do that kind of thing. Why is she playing people against each other? Why does she single you out? It's sad that she has pushed good teachers away. But most importantly, the stress she's casing you right now is awful.

It's so hard to stand up for yourself, I know. And not being used to people acting that way, it's hard to know how to react, and you just end up feeling victimized with no recourse. Is there someone over her head that you can go to? Can your friend back you up? It sounds like everyone is walking on eggshells.
