Don't worry about the car and the fine, I'm happy that the CAT scan showed no lasting damage and that in the end this is hopefully just a material thing, nothing affecting your health.
And please go a bit easier on your body, sleep deprivation is a great way to harm yourself permanently. Your body really needs that sleep and to push yourself past what is good for you is not something that you can equate with a 'couple of hours of sleep debt', it can harm you on a much longer timescale as well, even if you don't get into car accidents because of it.
