Meh 'Leepy

Grrr! I was doing so well, blogging every day. Last Saturday a wave of consuming fatigue swept over me and I haven't been the same since. I knew there was something very wrong when I couldn't finish an ice cream cone on Wednesday. This week I have been sleeping most of the day and all through the night. When I am not sleeping, I feel groggy and so physically exhausted that my own arms are weighty. My sleep is sound and rock-solid and I am not restless. I don't take confused glances at the clock. I am asleep within seconds and I don't move again until I wake. I've had some help this week. I went to the doctor on Thursday and had blood work drawn today. Dexter spent the day watching cartoons in my bed while I slept or read. What is wrong with me?
