Feeling faint and panicking while driving

Hi, I seriously need help/advice on what others do when they feel panicky and light headed while behind the wheel. I got into an accident in November and I was doing pretty great with driving but then I had a massive panic attack one day where I felt super light headed and like I was going to faint. Ever since then, I feel that way when I’m driving. I have even begun an anti anxiety med and have been speaking to a therapist but I’m struggling with this feeling and it sucks because I feel great except for when I’m behind the wheel or when I’m anticipating having to drive. Has anyone dealt with this and what did you do to cope?
