Oh my, I am sure you are not the only one to have a child overreact today. I think that this moment is probably passed, but in the moment, the person reacting that way goes to the bedroom to be away from people since that is not how we treat people.

And later, when he has calmed down, we talk about triggers and if this is what happens when you take a quiz, then maybe you don't get to use facebook, or whatever it was, for a while. Or, maybe a warning this time.
