Hey, i just wanted to let you know that i am 23 and i basically grew up taking care of myself, and i didn't learn to drive until last year, when i was 22 when i lived with my sister and she could teach me. i have horrible test anxiety and i am a good driver, but i already feel stupid being 23, and the first time the man yelled at me for shaking and i failed. i tried a second time, cried, and failed. i tried a third time (which is all you can do in a year in AZ) and failed again, even after practicing the 3 point turn and doing it perfectly 3 times, as soon as the guy started the test, i failed. i can't even think about it now without getting anxious. i just want to say you're not alone, and possibly someone out there has even worse anxieties about it.
i wish i had advice, but i still haven't gotten over it. everyone tells me to just breathe and concentrate, and it doesnt help. neither does hearing that i'm stupid and to get over it (in fact i think it that makes it so much worse). but i really hope you do better than i, and hopefully we can both overcome this!
