Why I dont like my math teacher

I am scared of my math teacher. Because of her I now hate the color purple and the number 2. Why? She always writes in purple and I failed both my chapter 2 test last year and my chapter 2 quiz this year. I used to be so good at math and I never had to study much but it all changed and now I'm struggling to keep a B! The first time I got a B i cried and now I'm relieved to get a B because I've gotten much worse grades. My friend and I's mantra before getting a quiz or test or lab back is: Please let me have gotten at least a B. Please let me have gotten at least a B. Please let me have gotten at least a B!
I even had 4 dreams about math already! Last year I had a test and I dreamed that I got a 96 on it and was showing everyone (I didn't really get a 96. I got an 85 or something like that). I had two dreams about homework: in one, we were supposed to "finish the page" or something like that and I only did the bottom half of the first page because I didn't know we were supposed to finish the entire exercises and she was yelling at me. The other was that in my agenda I wrote "Problems # 1-14, 23-13" or something like that and I didn't know how we were supposed to do 21-13 so I didn't do it and I was freaking out and thinking, ok I have math last today so I'll do it during lunch. and I knew she was going to yell at me. I don't remember the last one because I had that one second.
So therefore concludes my rant about my math teacher.
