Can't. Stop. Sleeping

I think I got hit with something. I'm not full-out sick, but I am just EXHAUSTED. I've been sleeping a ton since Wednesday. I stopped working around noon, slept till 1:30 when I went to pick up the mutt from school, came home and slept with her for another two hours. My stomach felt all off, and I wasn't sure I would be able to go to Franny's house for Thanksgiving.

Thursday comes around and I sleep till almost 11, after having gone to bed at 9, make a casserole and my mom's apple pie (both of which came out really really good), and then was so tired I thought I was going to fall over. Today, I slept till 10:30, went back to bed at noon for two hours, and I'm still exhausted. No energy at all.

I feel like I could sleep for a week and still be tired.

edited to add it took through Saturday afternoon for my energy to be back to normal.
