Depression? Or am I just not that cool anymore?

I'm not sure when it hit me today. Perhaps it was around noon. I had already spent three hours dictating to children, running on about four hours of sleep from the night before and that is when I realized I was probably going to trade my Louboutins for my linens on a Saturday night. So I came home from work and I went to bed.

On one hand it feels amazing. I had many options of things to do tonight and I chose to stay home and do nothing so that I could have a productive Superbowl Sunday and a productive start to my week. However, I can't help but wonder if this is the epitome of getting old.
