Even a couple of weeks is bad. I can see taking everything away for a few days as punishment for something but a few weeks? That’s still pretty harsh, never mind a few months. 

I’ve known kids who were “grounded” like this. It absolutely turns into abuse pretty quickly. And it never ends well. 

This is straight up abuse and OP needs to inform a school counsellor and/or their own parents bc calls need to be made.

I was one of those kids that was grounded for months at a time. It was terrible and depressing
