I know I was diagnosed with PTSD about a year before I thought I had any kind of problem. Well. I remember my first panic attack. In a laundry room. Something banged next to my head. Several millenia later I woke up to my sgt half pinning me talking me down. But panic attacks & nightmares & shit were normal & manageable for the crowd I was with at the time. So was reeeeally wild behavior bracketing periods of being really busy. Work hard. Play hard. So I really have no idea how long those were going on before I was diagnosed. I just remember it was about a year after my diagnosis that I broke.
As far as any singular event? Nope. It wasn't any singular mission, operation, deployment, or event inside of any of those. Unless you count the first... Which was the first time in my life I felt like I really came alive, found myself, & knew where I belonged. Here. Inside this moment. Doing exactly what I was doing. That was a total paradigm shift. Something just clicked. The world had color, and purpose, and meaning, and sense...for seemingly the first time. I've found that outside of combat, in pieces. But never as a whole. So IDK. Maybe it was that amazing moment. Maybe it was all the f*cked up shit, and pain, and grief, and terrible things that followed. Maybe I don't have PTSD at all, but NormalLifeStressDisorder, since normal life is what's never really made sense after that. Maybe it was the first time my emotions shut off, and I went cold and hard. Maybe it was the first time I broke. Or the first time my cracks started showing, and my compartments started breaking down. No f*cking clue. I've tried to parse it. As yet, it doesn't.
