I do understand. Those crashes can be very attractive, for a number of reasons. You do need to talk with a trained person, a therapist of some kind. And let him or her know the full version of what you've been describing here on PC. There's something behind that attraction to car crashes that you need to bring out into consciousness, and a T will help you to do that. It's not really a good thing to be attracted to car crashes, but the attraction won't go away until you understand why it's there.

I'm very, very happy to hear that you're not yet old enough to drive, which would make it a lot more serious than it is at present. But don't delay, tell your folks if you have to, but however you do it get to see a therapist as soon as you can. It doesn't sound like the hardest thing in the world to deal with and any trained therapist can help you fix this problem. Take care!
