I've seen the same thing happen to a number of people. It's simply people who only know how to live as if they're on a combat mission. Once they come back home and there are no bullets buzzing by, they realize they don't know what they were fighting so hard for - they realize they don't know how to live a 'normal' life. My dad is like that - when he has free time, he does nothing with it. When he doesn't have free time - he wishfully speaks of winning the lottery and having free time. I have a theory that people who believe life is about strife and that everyone's out to get them - when they finally reach a place where there's no strife and no one out to get them, they still continue fortifying against enemies that never come. The ridiculousness of fighting invisible enemies causes depression. It's simply a call to open up, to see that there's more to life than fight or flight.
