I could let myself feel sorry for myself: that I had to come home and take a test, make sure that my dog was taken care of, and then somehow muster up the energy to be fun and social at the end of the day, even though all I wanted to be was watching a TV show with some of my good friends on their couch. But I didn't. I came home, I faced my fears, and finally the pervasive anxiety is diminishing. I don't know how to let it leave every time, but this time I figured it out.
