Analysis of PTSD

Behold the aging soldier. He's grown longer in the tooth.
He wears the scars of battle that had squandered all his youth.
Although his war has ended, he finds much to his dismay.
The demons that now haunt him just don't seem to go away.
He performed his duty proudly as he served his time in hell.
The nightmares still upset him, but he hides it very well.
He tries to carry happy thoughts when he lays down to sleep.
But they will soon turn ugly 'cause his wounds are far too deep.
Outsiders just don't realize what may happen to these vets.
Their memories often fill them with a ton of life's regrets.
Try to keep them in your prayers so peace is what they find.
So many of them can't go on and they often lose their mind.
