nervous energy

I don’t know whether I’m nervous or anxious about driving from 11-13 hours almost non stop tomorrow. In the past I have driven from Switzerland to Spain, without stopping. In the past we had to stop to refuel but not anymore, not with modern cars. We have to stop for toilet breaks instead. During long drives I spend my time listening, either to books, or to podcasts. Recently I have spent a lot more time listening to books.
