Hi Dave,
I totally understand your fear of driving. I haven't driven more than a couple of times in the past 12 years, so I really know where you are. My only advice is to take the drive slowly, maybe break it into small parts where you drive a bit and then have a predertermined place...gas station, restaurant parking lot, etc., where you can stop for a few minutes and calm down and then start up again. Is there any way that you can get to your brothers without having to take the highway? I, too, dislike the highway, so I try to find alternate routes (when someone else is driving me). I hope you can find the courage and peace to make the trip!
