My best friend's mother had been driven everywhere by her father - and then her father dropped dead at work of a massive coronary, and her mom got her driver's license (at 50). She was so nervous she wouldn't even START the car because she was convinced that just with it 'on' she would lose control and kill someone. She's driving now (a Jeep) and actually enjoys it.

Also, I didn't get mine until I was 19 and am still an exceptionally timid driver - but I managed it . . . scary as hell, and I repeated driver's ed 3 times because I had a tendency to panic during left turns and lane changes, but I'm still alive and haven't killed anyone.

So, you can do it! I have faith in you. Try Keith's - they specialize in nervous drivers.
