A wall fell on me....

So I was sitting in an airport waiting area in Texas airport working on my phone while waiting for my flight. Suddenly, heard a sound and looked up and saw a huge wall coming at me.... Yup a wall. I put my arms and legs up to catch the wall and prevented it from hitting me directly in the head. But I received some bruising and minor cuts.
The contractors had built a freestanding structure that was 60' x 20' box and An entire 60' section collapsed..... On me and one other person. Because it was not supported structurally AND because it appeared as though the they had piled plywood against the unsupported wall.... Geesh!
My arms and were treated by ems (bandaid). Interviewed by police, fire and airport security....

If not for my own quick actions I could have been hurt badly. The next days I have been quite jittery both flying and during the day and l have woken at night "catch the falling wall" several times.

I am not American and unsure if there is anything that I could/should do? Physically ok, but could have been bad... Mentally a bit freaked out.

What should I do next... Just thank my lucky stars?
