What Day Is It?

As I was lying in bed Monday night, getting ready for the next day, I had convinced myself that tomorrow was Wednesday. I went over it in my mind, and I had definitely already worked two days. I spent most of my Tuesday thinking it was Wednesday, so it was quite crushing when I realized my mistake later in the day. So not only did I have to experience Wednesday twice, but now it's looking as though I'll have to do the same with Friday, as today definitely felt like a Friday. I feel tomorrow I should be able to sleep in, but alas, I must get up and trudge my way to work. Wish me and my fading mind luck.
