What can be worse than this?

Just had the presentation for IA and sitting at my desk now, I feel so……TIRED. Physically. My eyes feel sore and swollen. And as I think back to my presentation just now, I think it was good but it has to be the worst thing to be — to have to be energetic when you’re dead beat. When your eyes can barely open. When you don’t feel talking. When all you want to do now is just SLEEP.
