I don't feel so good today.
Firstly, I have a cold. Sore throat, general wooziness, sinuses filled with unspeakable substances, et cetera. Also, it doesn't help that I have an ulcer near the back of my mouth, which blends nicely with the pain from my throat.
Secondly, I'm suffering from caffeine withdrawal. Big cases last week, which led to drinking a lot of coffee. Now I've built up a mild addiction, which I'm trying to shake, which means I'm not feeling very good.
Thirdly, and this is the big one, I'm feeling really unmotivated at work. I transferred back to my old department at the beginning of August, and I'm having trouble getting into my job. This has led to a marked decrease in work quality, leading to at least one big spat with a client already. This is bad, because I've got another big and important case to do today, and all I can do is stare at it and think about how much I don't want to do it.
This sucks.
