I think it's because everything is so pent up - so much stress about school and uncertainty about what happens after. Yesterday, while at the student center buying dinner, I saw one of the university's chorus groups singing (I was drawn by the dulcet tones of Britney Spears' toxic). They were taking such joy in their singing, I was almost overcome with tears. Seriously, it came out of nowhere. I reminded myself that a) I was standing in the student center and b) they were singing freakin' "Toxic!"
Today, I spent another day in the library. I swear, sometimes it feels like this last weekend of studying is going to end me. I feel depressed and ugly and insecure about everything. I just want school to be over. These are the longest 3 days of my damned life.
