Dessert Nurse,

I am glad you posted this, because it is more than just choosing to" live a healthy way "

Anyone can get PTSD, no matter how mentally healthy they are or not. or what kind of past they have or not have.
Now your past and current mental health might determine how easily or hard you can recover from it. or you recover at all. But it isn't like, okay, today I will be live mentally healthy. I wish it was that easy. If you ever had one of my flashbacks or nightmares (which you can't control), you would then know a little how it feels. You can't control the automatic responses to triggers, where you body is ready to fight or flight. You can't just say, okay, now let me act mentally healthy.

This myth reminds me of the one who tells depressed people to just get over it and quite being lazy.
