What was I thinking?

12 units for Fall semester, working a whopping 9 hours a week, three hours of lab a week, and homework! I must have lost my damn mind. This is only the first week of class and I'm already freaking out. I'm not going to have time for anything. I will not have a life for the next three and a half months. Seriously I hope I only have one more semester until I finish, because I don't know if I can keep this up. This sucks!
