This happened to my aunt. She started avoiding driving on highways, a habit which ramped up over time. In her 40s, she became afraid of driving at all and wouldn’t drive anywhere. She went to therapy and is now able to drive again.

Avoidance teaches the brain that something is a threat. Exposure to that stimulus will retrain the brain to feel neutral about it again. I think the other comments on here gave some solid advice about this. But I just wanted to share this story so that you would feel less alone. It happens sometimes! And you can overcome it.
