Do you believe that only mentally ill people commit suicide?

I don't have figures, but it's always been my understanding that it's quite common that PTSD results from repeated exposure to traumatic stressors, that this is more the norm than developing PTSD from one or a limited number of events. Dissociative identity disorder (what used to be called MPD) typically develops from repeated traumatic stressors, and it has been implicated in borderline personality disorder. People who have been sexually abused as children can develop PTSD from the recurrent trauma. Even recurrent stress like from living in war zones, or constantly being homeless, can lead to PTSD. It's important to point out that PTSD is considered an abnormal response to life stressors. Some people can experience the same stressors and not develop the disorder. Others may experience seemingly normal stressors, such as living with an alcoholic spouse, and still develop the disorder. More severe stress, more repetitions, and other factors (such as feeling helpless) can contribute to the likelihood of developing the disorder. They have done brain imaging studies that show conclusively that a person with PTSD's brain doesn't function the same as a healthy brain, and reversion to normal brain function can be tracked with the intervention of therapeutic treatment.
