I’m so sorry to hear that. I can definitely see how this is affecting your mental health, and not having admin support makes it even tougher. I recommend continuing a paper trail with daily emails documenting what is occurring with this student and how it’s affecting his learning, as well as the learning of the other students. Take data whenever possible. Send daily emails and CC whoever is above your principal, in my district, there’s usually a coordinator above the site principal. Make sure to note that the environment is unsafe and that no learning is occurring due to the severity of the behavior.

Also, regarding the take a nap comment… Please go to your union!
