Today was a bad day...

Today was a bad day... It was pretty bad today for me. Nothing out of the ordinary schedule, had quite a few points to make in class (in grad school atm) and stuttered through the lot of it. Repeated the word 'He' like 7 times on one occasion. Drained all my energy and willpower, so much so that I started smoking again (had 10 cigarettes) after giving it up for a month. What didn't help was the cute girl in the second row who was looking at me weirdly, with disgust, like I was a piece of shit...
