Hi Jim. Part of the problem was something I didn't mention but will now. It was common for the parents of the players to sit right behind the team bench and openly make comments on every move I made during the game. If there were disagreement on a player substitution, for example, oftentimes I could hear the objection from the kid's parent. It would purposely be said loud enough to make sure I heard it. I knew this kind of thing was coming, and often this was a factor in the sleeplessness the night before. The overactive thyroid may well have played a role, and I know I was more prone to anger/snappish behavior after a night without sleep.
