Car wreck PTSD

So a month ago, the boys and I were in a wreck... not my fault...It totaled my car.

I have lived through many traumatic things in my life... However, I can't seem to shake this one.

Maybe it's because I'm still in pain from it.
Maybe it's because I HAVE to continue to drive on a daily basis.

Whatever it is... I am suffering major PTSD from it.

I pull over if someone is following too close behind me because I'm afraid they will hit me.
I jump if someone I am riding with pulls out into traffic even if the cars aren't that close.
I still won't take that road home that I got hit on.

Yesterday, I knew without a doubt I had been traumatized...

We went to Incredible Pizza where they have 4D movies.  We did the Jurassic Park one.  Unbeknownst to me, it is basically a car wreck where the dinosaurs wreck your car over and over and over again...

I walked away with fingernail indentations in my hands from gripping on so tight, a nauseous stomach, and a splitting headache.

Then last night I woke up from a nightmare where I was riding in a car with a friend and because she was crying so hard she didn't see the car in front of us, so I braced myself as we rammed into the car in front of us causing me to throw my hands forward and brace myself on the dashboard.

Then I woke up.
