So frustrated...

I'm at home, sick, today. I have no idea what's wrong with me. I just can't get up...but I'm not like depressed. I have NO energy. Last Saturday, I woke up at 6:30 am, went back to bed around 9 am, woke up at 1 pm, went back to bed at 3:30 pm, woke up around 7 pm, and was back asleep for the night by 8:30 pm. CRAZY! Yesterday, I had to come home from church because I felt like I was gonna pass out! And, this morning, I feel totally wiped out, when all I did was make a pot of grits! What in the world?! I have no sore throat, no headache, no fever, no nuthin'! Just no energy!! So stinkin' frustrating!!
