I don't think you should be driving. And please get seen by a neurologist as soon as you can. Blessings - Blu
In my experience anxiety can seem to come out of nowhere and turn something that is usually pretty routine into something that can be quite frightening. Have you had any anxiety issues in the past? Have you been under stress lately? Have you had an unpleasant experience driving recently? In my opinion, there are many factors that cause us to fear things that we did not even think about before. For me, the best thing I did was to go talk it over with someone that is trained in dealing with anxiety issues...learning about why I was feeling anxious helped me to better understand it and confront it.
