The song "Am I Awake?" by TMBG is a good description of how I felt writing my papers last week.

Am I awake?

What time is it?

When I get through this day
Can someone tell me how
And how much longer now
Am I awake?

The coffee's cold, did I forget to drink it yet
Did I forget?
My clothes are wet I don't remember drinking it

When I get through this part
Will the next one be the same
Will I be wondering
If I'm awake?

These are not the clothes I had on when I went to bed
And something else besides my hair is growing from my head
And when I close my eyes it looks the same as when I open them again

Am I awake?

What time is it?

Is it that time again?
Wasn't it already then?
So does it have to be
The time it was again

When I get through this day
Can't someone tell me how
And how much longer now
Am I awake?
Am I awake?
