The worst PTSD I ever saw was a friend of one of my buddies that I met a couple of times - he had been a combat medic with a SEAL team, so on top of being a medic he had some SEAL training. He saw some serious action but wouldn't talk about it. He was a little guy, but in peak physical condition and very intense, and holy shit anything could set him off. I liked him; he was a really nice guy underneath all that damage. As I said before I only met him a couple of times, and never had a chance to get close to him.
Despite his qualifications he couldn't hold a job; something would always happen to trigger his temper and he'd get whacked. He drifted from place to place, until he finally killed himself a couple of years ago. Either he never tried to get help or it just didn't take. Such a waste.
