Best of luck to you, Roxie!! And many prayers. You can do this!!! I used to feel the same way when I had to drive the 5 hours each way to my LLMD back in 2007. At least most of my driving was through pretty countryside and not in a lot of traffic.
Be sure to rest as much as you need to when you get back and I hope that you can rest well! We''l be here waiting to hear your wonderful report from your visit!!
