I started reading this thread because I liked the simple, direct way the question was put. Some good responses too. I particularly appreciate
@anthony weighing in with the official answer.
When I first joined this site, I honestly don't know if I had an official diagnosis or not. Probably did because my T had to tell the insurance company SOMETHING if he wanted to get paid. But this site has been a big part of coming to understand and accept the diagnosis, beyond a shadow of a doubt. You know how it goes. YOU have a reaction to something and it's a one off, or "just you", or "all your fault". You read a few hundred versions of the same thing from different people and it begins to dawn on you that maybe this actually IS a thing.
I can't help but wonder how people even KNOW who has an official diagnosis and who doesn't. (For the record, I never did do an introduction. Was I supposed to do that?!) Obviously sometimes it's clearly said, but not always. And, I'm not sure I care. For the people who really don't understand what PTSD is, and who really and truly think they have it because their SO left them, we can share the good news that it takes more than just that to remodel a brain. But I wouldn't discount the possibility that someone important leaving them could push someone over an edge that's been there all along.
Something about this conversation reminds my of what I think was my first session with my T. I hadn't told him much when I made the appointment. Had mentioned that an old friend had told me years ago that he thought I had PTSD and I was wondering about that. (What I DIDN'T tell him, until he asked again, a few weeks later, was that I was getting really tired of thinking about suicide all the time and thought maybe I'd try a different approach....) So, he started asked about potential reason I might have PTSD. "You know, like a bad car accident?" Well, there was the time I totaled the truck...... Or the time the thousand pound bale of hay flipped off the loader and almost squashed me, or the time I got dragged by a horse, or the other time I got dragged, or..... LOL I figured it was being molested as a child, because I KNEW that was on the official list. The rest of that stuff I thought of as "funny stories" because I didn't actually get killed. And, there was some other childhood stuff that I had no idea made any difference because I thought of it as "normal". Anyway, I have NO idea what, exactly, led to me meeting the criteria for an official diagnosis. I don't think anyone knows, yet, how all this stuff works to change the way a brain works. As far as the hallowed "Criteria A traumas" go, I look at that stuff as "things we know can cause it". This is science. It's evolving. The verdict is not yet in on what actually happens to rewire a brain. Whatever can do it, it's enough. Probably varies from person to person and depends on things we're only beginning to understand.
One more thought, on the subject of "attention seeking". I think people seek attention because they need it. Full stop. They may not need it for the reasons they think they do, but healthy people aren't "needy" to the degree that leads to the kind of attention seeking that annoys people. My instinctive reaction to "attention seeking" is a level of annoyance I don't understand. (Yet?) But I'm working on tempering that with compassion because, even though I don't get where they're coming from and it makes me very uncomfortable, maybe even mysteriously angry, I really believe people seek attention because they need it. If they come HERE seeking it, they are probably coming to the wrong place. It's not so much that THEY are "wrong", it's that there aren't a lot of people (if any) here who are going to be able to help them out. We don't have the resources. It's not what this site is for. Maybe we don't always handle those situations as well as we could?
