Every person is different. Though there are patterns and methods that are commonly effective, there are no hard and fast rules with emotional or psychological disorders.

As a vet, I associate with others who suffer from these types of disorders fairly often. I deal with PTSD myself, though to a much lesser degree than many. The one thing that I have learned is there is no one-size-fits-all cure or method of treatment for the depression or other issues that stem from this disorder. I would expect that any form of psychological disorder is similar, though I'm no expert and wouldn't be able to say for sure. I can only speak from my own experience.
