Another possible option.
I had a friend whose daughter had issues at school. I was home-schooling my own kids, so I took in her daughter to school as well. That was over 30 years ago, when home-schooling wasn’t near as popular as it is now.
I would do anything before I sent my child into such torment. Their education would actually be a secondary factor.
And God bless you for that.
There are ALWAYS options.
