I'm Exhausted

Being a co-assistant in hospital is exhausting and when I'm exhausted, I lose motivation to do things. I can't even bring myself to review material. It's also difficult for me to stay awake during lecture (yes, we still have lecture in hospital). I envy my friend who can stay awake during lecture and understand the material. They even have enough energy to discuss it with the residents. Seriously, those friends have no idea how lucky they are.

I'm trying though.
