My dd was diagnosed ADHD at the end of kindergarten. We went 18 months working with her teachers and doctor to find a medication that worked for her only to end up with a 2nd grader with suicidal thoughts (thank you Vyvanse!) So we took her off the meds and things at school got very rough moreso for her teacher than her. She was happy, eating and excited again but she lost what was left of her focus in class and it apparently sent her teacher over the edge.
I started getting reports from other parents that my dd's friends were telling them how mean the teacher was to my dd and a particular incident of her standing over my dd's desk and screaming at her until she cried. After hearing these reports I asked my dd about it and she told me what was going on but said she didn't want to tell me because she thought it was her fault because she can't sit still.
After all this my dd is in a really scary place for such a little person. She's not excited about school, she's blaming herself and she's become very emotinally needy. I made the decision to homeschool her in hopes that being away from that environment for the rest of the year I could help her build up her self esteem and get her excited about learning again.
I met with the principal and told her what was going on and why I was taking her out of school
