I also have terrible driving anxiety! I never really wanted to get my license but my mom was insistent that I get it. However she was patient and worked with me slowly over time to where I got comfortable. I finally got my license at the age of 20. The scariest part for me is the highway as well, especially merging. I'm 24 now and I still get scared that I'm going to get hit. It's gotten worse since I got rear-ended two years ago, ever since then I keep a close eye on my rear view mirror. Living in a small town with only one highway was easy, I could just go through town. But now I live a very big city and it's been hell .. it doesn't help that I don't know the area either. But I agree with everyone else, exposure therapy does help. I used to have panic attacks at the thought of being behind the wheel of a car and now I just get nervous when I have to get on the highway. I'm not 100% sure that will ever go away but I have to keep trying.
