What do you do after you're sure you're going to die, but you did not?

What do you do after a near death experience? I was absolutely positive I was going to be killed in a car accident this week. I knew it was all over without a doubt. There weren’t any other options. At the last minute another driver made a great move that saved me. It was a full sized SUV versus a small car, so it was pretty obvious what the odds were. But what do you do after you’ve made that conclusion? It’s still messing with me pretty good. We didn’t collide and I’m fine physically. It’s just got me thinking a lot.
