I've always been fine in a car but recently developed anxiety being in a car in the last few months

I haven't been in an accident, but some events including practicing driving myself I think have contributed. The reality dawned on me how easy it was to die and also i started being hyper vigilant of cars around me and the actions of the driver. Also my bf has fallen asleep at the wheel a couple of times, and i struggle to trust his driving.

Now i expect the worst and get scared of high speeds, lane changes, cars nearby, curbs, turns, intersections, everything. It's super exhausting to be constantly on edge while traveling.

I feel like if I'm gonna get therapy i need it for other reasons and i don't want to waste my resources on this. 

Who's beaten it on their own?
