"I hate you" is about the most hurtful thing that your child can say to you.
Just had the worst last hour with my son. He was overtired, but I have not had an episode like that with him in a very long time. Dealing with an overtired, stubborn six-year-old is always challenging; dealing with an overtired, stubborn, autistic six-year-old drains your body and mind completely, leaving you too spent to even cry. I know that he can't control himself when he loses it, I know I have to stay calm and just get him to sleep, I know that tomorrow is a new day and we'll start over and everything will be forgotten, but that doesn't really help me tonight.
