It's a very important problem, Simon, huge to you! I found it very scary learning to drive too. My father was my first teacher only he'd drive me the couple of blocks through our very quiet, safe neighborhood to the high school and then have me drive around the parking lot then drive me home; not much real world driving! My stepmother, on the other hand, the first time she took me on a practice drive she took me out on the multi-lane highway and busy little, narrow, country roads! I was scared to death going from a parking lot to such conditions!

Practice is a big help but here in the US we use to have school classes in driving and there would be 3-4 other kids our age in the car with us and the teacher, and we'd each get a turn during our classtime. It's nice to have others in the same boat -- anyway you can find or arrange for a "group" or second person to learn with you?

Or maybe you could get a counselor in addition to an instructor for the period you're learning to drive and work with them while you're learning to help with the anxiety some?
