@JLeslie – The OP says the car was totaled, so it was deemed not worth repairing by the insurance company – probably due to damage to the chassis.
I have been in a few serious car accidents, the worst and most recent in which I did a ¾ roll in a Mini Cooper S and walked away with just whiplash and a couple scratches. I loved that car and still miss it >3 years later. I had designed it and had it built for me; and it was the most expensive thing I’d ever bought, and I was proud to be able to afford it. It had previously survived a side-impact accident with nearly $18,000 of damage when it was 6 weeks old (to the hour!), which was not enough to total it since that was less than half the value of my brand new car. It took them months to fix it right! So I can relate to the attachment to the car.
I have not been traumatized severely from any accidents; but after that last one, I was freaked-out a bit and it all really comes down to the feeling of not having control. In your accident, you were driving a muscle car in the rain at night, and I have the impression that you are young and relatively new to driving which adds to an already risky situation. The Mustangs and Camaros are very cool-looking cars, but they still are rear-wheel drive, right? I just don’t think that they are a practical choice – especially for young drivers.
Have you replaced the Camaro? If not yet, consider getting a sporty car with front- or all-wheel drive, so you’ll have a better sense of control and better handling. Take a defensive driving course and refresh your knowledge of how to handle hydroplanes and skids. If you can afford it, consider an advanced behind-the-wheel course so you can get hands-on practice at controlling that machine. Always remember this: you can not control any of the millions of other people on the road, and far too many of them don’t comprehend how seriously deadly the roads are, and drive as if they’re sitting on their couch, rather than being alert and engaged with the act of driving. The best thing you can do is to educate and train yourself to be capable of handling a vehicle in treacherous conditions, and to practice zen driving. As the saying goes, getting back on the horse is the best way to overcome the fear after having been thrown.
