My English teacher is a sarcastic B*tch and now I have lunch detention? Help?

I'm the kind of student who barely talks in cl. I always do my work but sometimes daydream during lectures. Teachers have always liked me, so this is a first for me.. basically my English teacher is the b*tchiest lady ever. I hate her so much. She has no regard for anyones feelings. Theres been so many times in her cl that i've been close to tears. Recently I feel like she thinks im an airhead who doesnt pay attention in cl at all.. and thats so far from the truth. First of all on Friday I walked into cl and there was an overhead sheet on my desk. I ignored it and she came over later and glared at me and told me that it was unacceptable to find things on my desk and ignore them. In front of the whole cl. I was like 'okay' and hoped she'd smile or something but she just glared at me. Then we reviewed for the Odyssey and I was paying attention the whole time but she asks me THE one question I dont know. I told her I didn't know, and she rolls her eyes and says "well I dont think you're paying attention'. it was like a slap in the face. I was listening so hard the rest of cl but then people around me were talking and before I know it she was saying, "..no let's not start with Lexi. Let's start with Jessica." And I was like, FXCK and started rummaging around because I didnt know what to do.. and then i was like ummm.... ."what are we doing?" and she stared at me so hard and was like, "....seriously? what's going on with you? you need to come to 2nd lunch on tuesday, otherwise known as lunch detention." i was about to cry right there. i'm so quiet in class and i hardly ever talk, and it was just a coincidence that i happened to not hear her.. i really was paying attention and i dont know why she never even smiles at me or anything )): i dread seeing her now, what do i do? help?! i dont want her to hate me,
