Torn up and Spit out.

So I finish delivering my lesson and realize that I didn't get to the reading. I get so pissed at myself and my mentor teacher tries to calm me, saying that these kids take longer to write down the notes, and not to worry. Well, 8th period I thought I would be free of the harsh criticism of Mrs. A, but I could not escape it. She came in at the end of the class ripped me to shreds over my lesson. It really wasn't that different than the lesson the other teacher taught. And she has such a harsh way to criticizing me. She shoot me down and yells "No! You're Wrong!" She asked me to define "Golden Ages" and mid-sentence she cuts me off and yells, "NO!" "You must have a clear and precise definition, you need to know the content!" That was a basic question she was asking, that I was attempting to answer, but couldn't. So rude. I know she wants me to do well, but I have a weird feeling that it gives her a sadistic satisfaction to shoot me down. I can't yell back, I won't yell back. I just need to survive at this point. I hate being spoken to in such a degrading way, and having to take it because I don't want conflict. If I did even say one thing back to her, I know it would blow up and permanently wreck the somewhat decent relationship I have been able to maintain with her. I just need to let her scream and yell, and somehow not let it bother me. Challenging, I know.
