Such a looooooong weekend

It official, this is an extremely long and extremely stressful one. I'm studying my butt off so that I can hopefully graduate in December and that truly was enough to make it a long weekend. Organic Chemistry and I just don't get along. However, other things have made it even worse. Why is it that whenever I need a specific question answered I have to wait until Monday at 8 am. I'm tired, I'm burnt out from studying, I just want to have Monday over with and have my pilot back. I'm so over stressed. Now i'm legitimately worried on top of everything else. I should have just followed my instinct.
