You say you can't drive. Do you mean you're unwilling to drive? There are different reasons people are unwilling to drive. Some just don't want to. My wife had vision problems when very young and just doesn't feel confident that she can see well enough. If you don't drive because you're afraid to without a real reason for it, that's a phobia and an anxiety problem. I also don't quite understand why fibro would make you unable to drive -- cars haven't needed much muscle to drive them for a long time now, everything is power this and power that. As you describe your experience, it sounds like you're having a phobic reaction even as a passenger. If that's how it is, therapy with someone who specializes in the treatment of phobias might free you from this fear.
