Buried in work

I don't think I have spent so many consecutive hours at work/working before. At least, it doesn't seem like it. Part of the issue is having morning classes: if I arrive at 10 or 11 for two afternoon/evening classes, then work till 8, that's one thing. If I arrive at 7 or 7:30 to prepare for morning classes, but still stay till 7, I have plenty of time to go home and work some more before bed. Then, I crawl to bed, glaze-eyed, dream of new lessons to give, and get up at 6 AM again to make them happen. It's strange. I'm exhausted, but have that satisfied feeling from work well-done. (I still maintain my Mr.-Magoo-type confusion and disorder in class; who knows if students can recognize the work I put into preparing for class with my wacky confusion, especially if you are like me and insist on new assignments and slides every term.)

On the weekends, I work on my projects. I run to catch the sun rise or the sunset. (Last weekend also involved a school function.) While my projects give me a different kind of satisfaction, I wonder if I am missing out on the normal "destressing" type activities. They say you should have hobbies to decrease your stress, but if your hobbies are also your work... I can't tell if I have less or more stress.

I can't figure out how a personal life or a family life would fit in.
