At first I thought it was because I had no time to relax when practice got out, I believed that my mind was still in that coaching mode. The odd thing is that my coaching mode is to explain what someone did wrong before I even think of yelling. One day this week I figured that I would go workout after practice so that I could get some of that anger out while I ran or lifted, I had no luck.
My second thought was my blood sugar, the last two nights however I was getting home with a blood sugar close to 140, so that couldn't't be the reason for the bad mood. I then thought it could be because I'm hungry, once I eat dinner and watch a little television I'm back to normal and laughing. For the past two days I had a small snack during practice, this did not change my mood after practice however. Now I'm out of ideas, the only thing I can think to do is to drive around for a little while and try to unwind. I have had moments like this in the past but nothing this consistent, again I'm out of ideas and would welcome any and all suggestions.
