Just so you are aware, there can be more than one event that causes ptsd. Childhood abuse over a period of years can start it off, but as a child, you don't know those symptoms are not normal. Assault can add a different set of triggers that activate your ptsd. Does that make sense? Then when you add death onto that, accident, war: foreign or domestic, etc. My goodness. It can get really tricky for a lot of us.
The first break-in of my home and captivity for a few days set mine off since afterwards I was hyper-vigilant. The sounds, smells set me into a frenzy of fear so bad I could not move. When someone got too close to my body I jumped back or sideways. My arms would fly up to protect my face. I'd scream or cry over just about nothing. If someone made the mistake of touching me when I didn't know they were there, I'd attack them. I thought I was going to be killed if I didn't kill them first. Many years later, after I'd learned how to ground and get it together, I was in a 7-11 and it was held up by a gunman who killed everyone but me. He thought I was dead. He shot me in the leg and because of my past abuse I knew to lie very still til he was gone. Reactivated my ptsd and it took a long time to calm down again. Over the course of my life, I've healed enough to function, then had another trauma and it comes back.
They say you can only die once, but I'll tell you what, it's not the death that scares me. It's the living without being able to defend myself that is death to me.
Sorry to ramble.
