Calling All Energy!

What happened? I don't know what drained me yesterday, but I couldn't find the energy to do anything! I managed to squeeze in a little boxing, but I quit after finishing a simple routine because I felt like passing out. Perhaps my sugar was low? I'm not sure, but I did not get anything done around the house, either, except for school and dinner (which wasn't good!). I will try to do better today, since I've already cleaned the living room and I slept much better!
