Scared of driving alone

I’m 19F with a license, got it at the end of June. I’m just scared of what happens if I have a seizure in the car alone and get into an accident or forget how to drive. My memory is so bad, I can’t even remember directions. Right now my seizures are under control by of 300 mg Lamotrigine, I take anxiety medicine and ADHD medicine. My doctor told me that I could drive. Before I drive, I take deep breaths and think about good things. I only feel relax when I’m driving with my mother in the car. My mother gets mad at me for not driving all by myself. Is there anyway for me to stop feeling scared of driving alone.
