I can't sleep!!

Took an unexpected nap (as in, I lied down for a few minutes and next thing I knew 4 hours had passed) earlier and woke up at 9:30pm. I got up and had dinner, and then got into an argument with my mom. I'm still worked up over it. And now it's 1:30am and I can't go back to sleep... I'm going to be so sorry for this in the morning. Work at 6am. Ugh.
