I too am learning to drive. I had to switch instructors/schools because the previous guy wasn't very helpful. This new guy is very in-depth and informative. Maybe a different instructor will help? Someone who's better a dealing with anxious learners. I get a little bit nervous, too, and sometimes get a bit tunnel-visioned. Not literally in the sense that I don't look out but I might tend to slow down when I do or forget which gear I'm in (learning stick).
