I've been prone to fainting in certain situation through my life (mainly whilst in the dentist/doctors). I'm only 25, but since I started driving a few years ago I've probably covered around 100,000 miles. I loved it. However, earlier this year I was on a long drive whilst listening to a science podcast that on this specific episode got quite medically graphic. I also hadn't eaten in about 9 hours. Thankfully I'm used to the signs and was able to safely pull-over on the breakdown lane. However, I did then faint. Speaking to my doctor, I was okay to continue driving due to the seemingly preventable nature (keep blood sugars up and don't listen to medical things!). However since that event I have increasingly bad anxiety about fainting again whilst driving. I know I've never spontaneously fainted, but whilst driving I now virtually always start to get sweaty palms and feel a bit faint. It is so predicable that on the highway I feel less faint the closer that we get to the next exit, and worst when we've just passed one. So far I haven't let this anxiety affect my life, but I can feel it is getting worse. Any advise greatly appreciated.
