I'm so Tired

Don't know if this is a new symptom that creeps up around this time but I've been beat in the past 3 days. What sucks is that I have finals and I should be studying but instead I took a nap after my final yesterday, then I went back to studying till really late but then I woke up late so I don't think the studying really late helps. Instead I'm going to try to study all day and sleep early tonight so that I wake up refreshed for my 3 (out of 4) final. I woke up at 11am, my mom went on Bubbs field trip with him so she got him ready and Steph woke up with Audrey and fed her so I had nothing to worry about but this is lame, I can't be doing this. zzzzzzzzzz I can honestly lay down right now and fall asleep, but I won't! I must study!
