No, not quite over the edge. PTSD causes the thoughts/thinking to be illogical, irrational. THAT IS THE DISORDER...not you.
To feel in control, be in the "element" of war, battling it.... there. Here, you feel powerless, it's a mind game you have to win... constantly tell yourself what you are thinking and feeling is irrational. (And they you begin to question if that isn't also your being irrational...what is real anymore?)
I was injured in a thunderstorm...so the thunder, fireworks, backfires etc yeah all trigger me. Not so bad now, after 21 years... but how can that be encouraging? If someone had told me it would take this long to even begin to feel normal sometimes...

guess that's why they didn't share that. My T had said it isn't curable, but that I can learn to live with it, and have a life... so at least he didn't lead me astray..and he's still hanging with me.
