Is it normal that after almost dying i'm not as afraid?

I was in a car accident where I was t-boned and my small pick-up flew in the air landed on its roof then rolled another complete time and landed upside down in a ditch. Immediatly after the wreck I crawled out of the back window dazzed with only a very small whole in my foot and cuts all over my legs and a huge headache. Everyone was starring at me amazed i was alive. I looked at the truck and thought I must be a ghost but people started asking me if I was ok. The ambulance came and took me to the hospital and I was totally fine. The next day I went to see the truck turn right side up and the thing looked like it just got back from a monster truck show. There didnt look like there was enough room in the cabin for even a small child to fit in. I'm 18, im training to become a marine, and Im very strong and tough but I theres just no way I should have lived that. I now believe I must have been saved. I think my girlfriends love is what protected me. I really believe she is my angel. No one loves me more then her. But now Im alittle worried cus im even more wreckless then i used to be! not that thats why i was in the original acccident, that was because i tried crossing a 4 lane road and my trucks clutch was very very old and worn out and it was slipping very badly when i tried acclerating it didnt go anywhere. It was such a scary experiance.
