As a teenager I witnessed an episode of PTSD before the disorder was even listed in the DSM.

Of course, I didn’t know exactly what I was dealing with, but instinct served me well.

My mother and I were travelling together through Europe on a Eurail Pass.

We were in the German-speaking part of Switzerland, waiting for our train in the station. All of a sudden, my mother became anxious and told me she saw Nazis everywhere and flags with swastikas.
