It seems I've been working myself harder than I knew. Was very tired yesterday, despite having slept like a rock the night before. In the past, I wouldn't have allowed myself to rest, telling myself 'you've already had a full nights sleep, stop being so lazy!' Not listening to my body has sometimes caused me to become very depressed. So I made sure I squeezed a short nap when I could, just 20 minutes. It improved my mood considerably, and helped me get through my last two lessons. Then I decided to head home instead of dancing last night, and sleep I got from that has me feeling better still today.
