I'm driving myself nuts!

Why am I so freaking nervous about this freaking job?! I'm worrying myself sick. I'm obsessing. I can't sleep, or I sleep way too much. Tuesdays and Thursdays would work better for me, and a different location would be so nice. This one is just icky. Beggars can't be choosers, I guess. I've been out of work for a long time. I'm just obsessing because I have to learn everybody's name, get everybody signed in, take notes about each person, AND the psychologist already talked to me about being too shy...I need to talk to people and be friendly. It was my first day, for crying out loud! And luckily, the girl I'm shadowing is coming back tomorrow, but then Monday, I'm on my own. Total panic. I mean, it's not a hard job; I just need to get comfortable with the names. ugh.
