He can't sleep. He wants to go to sleep but he can't. This happens about once a week. I've explained sometimes people can find it hard to get to sleep but he gets himself so stressed out it's like he's trapped in a vicious circle.
I've finally managed to get the crying and shouting to stop and he's lying quietly.
I feel awful for him.
He's at his wits end. I'm at my wits end. And now I want to go to bed!
