Something is wrong with me.

I know that is stating the obvious, but seriously, something is wrong with me. I have been doing nothing but SLEEPING. I go to work at 8 am, get off around 4:30, then go home and sleep until the next morning. I also sleep all weekend. WTF? I only have 1 job now; you'd THINK I would have more energy, but no. Total and complete laziness. My house is such a mess right now it makes me twitch, and I can't remember what my husband looks like. Could it be the heat? Am I depressed? I don't know. I feel like an uber-sloth. I haven't worked-out in days (that could be the problem) and I just don't feel like doing shit. I've tried to make myself do stuff, but I end up all whiney and crabby. I am going to go get some blood drawn to make sure I'm not anemic or something. Coffee isn't even working.
