School is dry

Day 2 and I've already lapsed in and out of consciousness in one of my classes. I have noooo idea what the professor is talking about. I didn't even take economics in high school or university!

Class hours aren't bad, but I feel as though the work is going to start piling at an exponential rate if I don't start now.

I've been feeling a wide range of emotions lately. I'm getting irritated with people when I'm usually quite easy going. Sad that this is my last semester of classes and exams. Happy that I'm going to be done my 4 year journey. Scared of venturing into the life of being an adult. Not looking forward to working for 30+ years.

How do you take your mind off something?
