["I recently got a new job in a city three hours away in an industry that I've never worked in yet. I'm a bit nervous, but at the same time I'm excited."]
Congratulations, I'm sure you will do great.  it's always nerve-racking the first day of work!
I'm moving to a new city and starting a new job in an industry I've never worked in. I'm both excited and nervous at the same time.
