Please pray for driving fears

So all the way from teen to last year, I've dealt with mystery undiagnosed dizziness and health issues that came and went that affected my ability and confidence to drive. It worsened any normal levels of driving anxiety. I loved life so much that I didn't want to leave this world and my sweet husband. Last year I became so depressed from different health issues that were not necessarily dizziness that I finally got the confience to drive because I was so depressed and hopeless that I wasn't really concerned if I died or got hurt, and I wasn't intentionally trying to hurt myself or others, and I tried to follow all of the laws and regulations and be safe, but I was at such of an "end of my rope" breaking point that where I figured I may as well start driving and doing something productive with a chance to better my life, or die trying. And I got better at driving than I ever have before on a good day. Well my health has improved a lot but now that I'm going on the expressway, I must enjoy my life a lot more now again because it scares me a lot and I cannot understand how people do this every day for an hour or more and then proceed to work st a stressful job. Please pray and give me tips on overcoming this fear of getting in a wreck.
