About a month ago, I had a near death experience. I was almost hit by a diesel truck head on. Every since then, I've had this huge fear of dieing... It's not death I'm scared of, it's the unknown of how and when I'll die. Will I die a long painful death, will I die at a young age, etc, etc... I lay in bed at night crying and can't get to sleep because these thoughts consume my very being. I can't even drive anymore without feeling panicked and scared. I'm nervous the whole time I'm driving until I reach my destination.
Is this normal? How can I get rid of these thoughts and just enjoy what life I do have? This really bugs me.

I'm terrified.
