Why does my science teacher hate me?

So I have had a teacher that is the worst fricking teacher ever (Not saying any names!!). This teacher hates me sooooooo much its not even funny!!. She is my 7th grade science teacher and she is ugly as sin she looks like a rat. This is wierd and I might just be a sensitive person but... SHE MADE ME CRIE TWICE!! That *****. Okay so it all started when I was on crutches. I had a helper take my books and we would leave 5 min. early from the cl. Well I was leaving one day with my helper and another girl broke her foot and she was leaving (without a helper) and so the helper was taking my stuff and im just standing there waiting. The teacher turns around looks right at me and yells: "LADIES YOU ARE DISRUPTING MY CL!! GO OUTSIDE WAIT FOR YOUR HELPER AND JUST LEAVE!!" So I walked outside and that was the first time I cried. The second time she made me crie was when she accused me of cheating on a test... not once but twice. The first time she accused me of giving another student my answers. Then the second time she accused me of writing an answer on my hand. What I wrote on my hand was not even for science. It was for social studies!! It said proclamation. So the ***** asked me what I wrote on my hand and I said I wrote it this morning and really lud she says: "YOU HAVENT WASHED YOUR HAND SINCE THIS MORNING!?" Of course I washed my hands but it didnt come off yet!! She didnt even let me explain that or what it said. Instead she made me go wash my hands in front of everyone because there is a sink in the clroom.
