I'd put some of that anxiety aside, most judges won't care what you change your name to. It'll most likely go through great, without a hitch; when I went for the name change, the judge didn't take the bench for anyone there, and my mom also pointed out that people change their name to Batman, for all the judge cares. So long as you're not evading anything, such as debt, a criminal charge, etc, you'll be fine. Enjoy this big step, and don't fret!
