I have driving anxiety too. Very much. I'm happy not to be the only one, but unfortunately I don't know other people with it in real life, so I feel very uncomfortable. I could never do some things that you all do, though you have anxiety too (like driving alone..I never did). The point is that I get terrified even for small things that happen when I'm driving, like a narrow point to go through...maybe at the end I do it, but I go on feeling scared for a long time. I know that I shouldn't avoid driving, but I do. I wish that I could find a solution But I don't have ideas that don't sound scary.
Wish you all all the best with this.
