Hopefully once you've been driving for a while and get a feel for driving you'll become a really confident driver. After a while you start to feel the car is an extension of you and you also pick up a sort of sixth sense in what other drivers are going to do before they do it and driving becomes like breathing. I can honestly say that when i'm driving in my car (sounds like a Madness song :b ) i'm at my most confident, and I hope you'll be the same.
That's awesome. I flunked my driver's test twice as a kid due to anxiety and passed the third time. Having your license is great! Enjoy it, its so freeing once you know how to drive and don't have to rely on others for a ride!
