Oops. I think I misunderstood. I thought she meant did our PTSD get worse after a car accident. So let me start over.

I did not get PTSD from a car accident. I had it long before then, and yes, it did get worse for awhile afterward.

And you're right, though. Not everyone gets PTSD from a car accident. I'm not even sure how long PTSD would last from something like that.
