Hey kharahlyn,
I hope you'll keep visiting. I know what it's like to feel overwhelmed by everything you have to do. But take some hope--lots of folks here have been in this position and managed to work something out. Doughnut has a good idea--take it a little bit at a time. For example, you're not taking time to eat and then you end up starving. So, one thing you could do is make sure you have a supply of healthy snacks that you can carry with you and eat when you suddenly realize--my gosh, I didn't eat! There are lots of such things available these days, and they save my life when I'm busy.
