I blast my AC to cold. That somehow diminishes the anxiety. As if my body is now focusing on trying to be warm. I also found sucking on Halls Candy has helped me feel calm. Bring cold water with you. Apart from that, if I'm anxious before i start driving, i take Hydroxizine 30 minutes before driving.

I had to do slow breathing in through the nose and out the mouth. I’d also get dizzy when I had them so driving seemed kind of dangerous at first until I got used to them. I had heart palpitations as well so whenever I’d get them I’d have to feel my pulse to reassure my self I was okay. It felt like my heart would stop and it’s make me even more anxious. Calming music or nature sounds. Pulling over is smart until you can learn to manage them. I’m so sorry you are dealing with this. It just makes life so unhinged.

Start off by breaking it down into smaller chunks, start by driving a very short distance then come back, do that till your confident then increase the journey slowly then over time your confidence should strengthen and hopefully you will feel better about driving

I get dizzy when I drive too, when I'm having it I noticed it helps alot to grab on to the back of my neck while it having it or stick your hand out the window, weird but it really works
