Like most people, I am a weird mix of introvert and extrovert. I also have anxiety, which makes life extra interesting. It's not just nerves, and it's not a normal level of stress, even for a graduate student. It's hard to tell what normal is, though. Anyway, anxiety manifests itself in various ways. One, I hate calling people on the phone and am eternally grateful to whoever invented texting. Just the other week, I had to call someone to cancel an appointment because despite the handy online appointment making tool, they provided no way to cancel that appointment without calling. I tried to call after hours and leave a message, but there was no answering machine. It's a trap for introverts, I just know it. But I managed to make the call and I didn't have to leave the house for the appointment. I'm perfectly capable of calling when I know I have to do it, but I have all these worst case scenarios come to mind, like dialing the wrong number and accidentally saying something ridiculous... yeah, anyway. Anxiety isn't rational, all right?
