nah don't feel guilty if she was a cunt. I've had battles with teachers.... ok storytime
I used to fight with my 7th grade teacher, she was horrible man..... and now I give you BP Confession #25637.77 which is that she left me back and failed me. Yes folks I got left back BUT I didn't complain to the adults correctly.... hey I was a kid. but after my mom and I told the school board what was going on, the school board agreed to put me in 7th grade for the first part of the next year to prove/monitor how smart I was. Of course I got all A's hahahhaa and very high regards from my new 7th grade teacher. So they with egg on their face:
1. I was promptly put into 8th grade class. The kids that didn't know me put a rumor out that I was a brain child skipping 7th grade

--- and I got straight A's in 8th grade also.
2. Miss Faback (original 7th grade teacher was never allowed again to be employed full time in our district ever again. It was awkward when I had her as a substitue teacher in high school..... and yea I asked her "hey why arn't you full time?"

now if you ask me about my high school Spanish teacher, don't unless you want another long post

.
So yes .. complain in your case. Many teachers are cunts and get away with shit.
hmmm I got a good one about Miss Tracy... :/ .... totally controversial.
and if we go way back..... complained about Nuns physcially hurting me..... ok BP Confession #25.64111 right there
