Sorry to hear about your accident, but atleast you walked away from it, and no one else was involved. Bloody lucky with the insurance too. I had a pretty big one a few years back in a hatchback, ended up going backwards into a tree, and have to say, it does make you a more rounded driver, as you are aware of other factors, and the experience just makes you think a little deeper. I had a massive spin in the Zed last year at Bedford, (that last corner), luckily it spat me onto the infield, not the pit wall, and i never took that corner at serious speed for the rest of the day, and it took me an hour or so to get any sort of confidence back in myself, and the car. I carried too much kerb on the apex, and though i thought I had the drift under control, when it snapped the other way, it was out of my control. You will get there, and be a better driver because of it, just takes time. Maybe go out in the car again, if your mate lets you, and go for a gentle drive.
