Yes, I have had very threatening teachers when I was in school. I don't think that we had school psychologists when I was in grade school...at least, I don't remember.

Interesting that the school psychologist has heard about this teacher from others, and yet she is still working there. It's definitely worth mentioning to your parents, so they can bring it up to the school principal immediately. IMO, teachers shouldn't ever be allowed to use brutality or emotional abuse to motivate students to do their work. It's ineffective and unacceptable!

Please do talk with your parents/caregiver(s) today. Gentle hugs to you!
