I also wanted to recommend the phobia and anxiety workbook: http://www.amazon.com/Anxiety-Phobia-Workbook-Edmund-Bourne/dp/157224223X

You may find that using this book while working with a therapist is helpful, since therapists can serve as the gentle but firm motivation needed…something that can be hard to find with other support people in one’s life. Speaking of support people, the book has tips for them too, so if you have someone who will be travelling with you they’ll have an idea of how they can help. I went over these tips with my husband before he went driving with me, and I think it helped us both to stay focused and know what’s helpful and what isn’t.

Also, since I’ve written this post I’ve noticed that my anxiety has lifted a lot. I don’t know if its because I’m facing it in a new way- being open, honest and willing to talk about it in a public forum….but either way I think just talking about it here has helped.

I guess all this is to say that it is possible to get over a phobia even though it feels like one of the hardest things I’ll ever do. And you can do it too!
