 25 weeks pregnant here and let me add I drive all the time without any issues. However -I was driving today to order a cake for my baby shower, maybe 20 minutes from my house not far at all local streets no highways.  I started to develop anxiety and barely made it to the bakery. I freaked out, my apple watch showed my heart was jumping 83-110 every few minutes which freaked me out even more. It went away right as I got out of the car and the whole ride home I had to call someone to make small talk not to focus on whatever the heck was going on in my brain. I still felt anxious during the small talk but I tried to focus on talking. I've never experienced this before and there really was no trigger that I can think of. Can anyone relate? Or offer advice on how to cope with this if it comes back again?
