I sadly can't offer much advice but you're not alone. I wasn't afraid of driving at first, I enjoyed it, but now I'm terrified.

I'm a very insecure person. My boyfriend has been driving his whole life, he's a mechanic, and he races cars recreationally. I met him shortly after I learned to drive an automatic and got my drivers license. He was always making jokes like how he only dates women who drive manual and a monkey could drive an automatic and he's taught people in like a day how to drive manual and I tried to learn but it was just so hard and I felt like poo about myself because of comments he's made. He's stopped and he hasn't said anything, but it's in his car culture like when we go to his sports car club meetings people are always bashing on people who can't drive manual. Now just thinking about it makes me cry and it's spilled over in to everyday driving. I'm terrified now and I get so anxious and unhappy.

I also can't handle any critique from him like he said I turned a bit fast when we were driving together one day and I just snapped. I was so nervous to drive in front of him because I was worried he would critique me and he did which made me feel worse and I just took a fit. I haven't driven in months.

I hope you find something that works for you and find someone to help. I know it sucks but I hope things improve for you
