I saw something where they took an old WWII vet, with psychologists and others, to a city that he had fought in that gave him PTSD nightmares for decades. He was scared to go back, but when he did, his PTSD went away because he saw how changed everything was and you couldn’t tell that the war had happened. That allowed him to recognize that the danger was gone and over.

that’s very different from revisiting a place that something bad happened just because, though. This was 40 years later in a city that was rubble when he last saw it.
