What the hell is going on with me this quarter?

What the hell is going on with me?  I can't concentrate, I can't study, I can't understand how to do something even I keep studying and practicing.  What is happening?  During the beginning of the quarter I was doing well, I even got an above average grade on my organic chemistry midterm, but then everything changed.  I started to get below average scores on every one of my other midterms, even on my second organic chemistry midterm.  Was this because I acted like an asshole towards Julie?  Are the Gods punishing me for my arrogance?  If so, I'm sorry, please have mercy.
