It's never diagnosed either.  I was diagnosed with PTSD at a teen after years of terrible abuse as a young child.  Once I was diagnosed, I went to therapy, began an exercise program and learned techniques to help me deal with my disorder. I am also careful to structure my diet in a way that helps support my nutritional needs and fuels my brain with what it needs to be healthy. PTSD doesn't really go away because the trauma changes the way your brain is wired, but with a bit of work and effort, you can learn to manage it and go on to have a happy life. Sure, I could have given up and surrendered to eating 30,000 calories a day, but that wouldn't solve anything.  Fatties gonna fat I guess.
