I can't drive and TBH it's never been too much of an issue, I accept lifts from people if they offer and it's not out of their way but 99% of the time I walk everywhere because I enjoy it.
I am 22 have had 23 lessons and my confidence with driving is rock bottom.
Noone has ever ridiculed me for it although I have had the odd 'god I don't know how you live without it', but that's about it although my mum did buy me a provisional and driving lesssons for my 21st birthday (subtle hint I assume ).
I ask for a lift if I really have to in an emergnency but again that is maybe once a year.
I do intend to pass my test in the next year or so but as it is I don't want to get a car, that may change but our finances are shot as it is never mind with the expense of that too. I do intend however to hire a car if I am say driving to Glasgow from teh Highlands to visit family and friends IYKWIM, but if money gets better I will be getting a car.
Have you seen a counsellor about the accident fairbags? My gran had an accident when she first started driving and was off it for a while but she saw a counsellor and was advised to get a friend or even a few driving lessons to take her out to a quiet place and start over, then gradually as her confidence went up she would move onto a busier road until she was driving about happily again.
