A kind-hearted pegasi stallion named Typhoon Blitz works at the new pool area that opened. Typhoon Blitz was a human named Anthony O`Neil, a war hero and combat vet. Before he reincarnated into a anthro pony, he had heart cancer and past away. Despite of living a peaceful live in anthro Equestria, he still suffers PTSD, and still haunted by the moments of his time in war. He was still haunted from his past, until he met Princess Luna, Princess of the night, and they befriended. But afterwards, they got closer than being friends.
This story may contain some sexual elements, but small amounts. This is the story I thought of making a story based on warriors/soldiers affected by PTSD. The image is not mine, it was found on Derpibooru.org.
