Those who are afraid of spiders start off by just looking at pictures of spiders and reading about them. For me, when I couldn't even get in a car and drive, I started reading my state's drivers ed manual, getting familiar with safety and traffic laws. I've real a lot online about driving phobias. Also, looking at Google maps can help you get a sense of where roads and exits are near you.

I hope you can take the first steps, it is hard but you can do it!
