Songs like this are one way of coping against PTSD and thoughts of suicide. It is a musical form of therapy.
There are several therapy groups supported by Veterans and the Veterans Administration (VA) that utilize songwriting in their therapy.
I believe the effectiveness of musical therapy is much better recognized and understood now than it was decades ago.
The Charlie Daniels Band had a minor hit with a song called "Still In Saigon" about nightmares.
