I wake up and spend the morning thinking that life sucks and I'm miserable and depressed, but then I remember I'm just sleep-deprived and that's fooling me into feeling that way. Then I vary between sugar highs and circadian lows till I get home, at which point I enter into a rather numb period. Then I go to sleep. With all this variance, an overall summation is hard to do.
