I suggest having a good friend or your SO teach you to drive. My best friend taught me when I was 15, she was very calm and rational about everything - even when I got into an accident in her new truck.
DH taught me to drive a stick some years ago. He was also very calm and reassuring about the whole thing, and it only took me a few hours to get the hang of it.
When I went to driving school, I was very scared and intimidated - both of the actual driving and the stranger sitting next to me. He wasn't laid back or relaxed, and it made me even more nervous.
Either way, living in Alaska, I'd suggest doing it soonish. I can't imagine learning to drive in 2 feet of snow would be very fun.
ETA: You posted while I was posting. Why not take a day trip to see his family and see if one of them can spare an hour to help you? Even driving for a little bit, successfully, without a bunch of stress might help you relax some for the class.
