I understand, I have bad driving anxiety too. I have the license since several years but never drove alone and also with my parents I drive rarely. Now I decided to go back to driving school (not the one where I went before, because the instructor was rude and gave me anxiety; luckily my new instructor is better), and I'm maybe feeling a bit more comfortable, but I still have many steps to do, like driving alone
Could you find a second instructor? Maybe ask suggestions to your friends to find a good one.
Good luck to all who are learning to drive
