Yes, indeed, someone can help, though you may not happen to have a good local psychologist in your specific small town, it'd be well worth your while to seek one out, with your dad's help, and get treatment for this phobic anxiety, which is much more common than you may think. CBT ( Cognitive-Behaviour Therapy ) can work wonders in a situation like this, helping you to fairly rapidly unlearn the habit of fear in regard to traffic and driing in it, and to be able to relax and function well in such situations. This is the best treatment available for such problems. Be cautious about suggestins, which a GP might make, of using tranquillizers, as these are rather like alcohol and impair your reactions times, and on significant doses of those, your reactions may be similar to being drunk.
