What hurt me was that I was actually admiring someone here (Not romantically!) And what I got was an exremely rude response. I was honestly thinking I was giving someone good advice, (Not in a look at me I know it all way) And there is no thankfulness, no interest. This sucks... I cant even be angry about that person, because its not about the other person/persons.
Something it helps to remember is, posters here are mentally ill. One of the big symptom sets in PTSD shows up as problems with self-regulation. You might be giving great advice, and solid support, but the person you are giving it to, or someone else reading the thread, might have some sort of symptom-based reaction at you.
That reaction is their own - and the useful thing to practice, is re-writing that inner script that tells you that you are being judged, or criticized. That they don't like you or aren't listening.
With a place like this, all you can do is put it out there. Think of your responses as messages that go into a bottle. Maybe the bottle will make it somewhere, and maybe it won't. But hopefully, in writing it out, you also got something for yourself - maybe affirmation that you have something to contribute, maybe it helped you figure something out. Maybe if you read your advice to someone else, you'll see how you can also apply it to yourself. And maybe, it was just giving you a distraction for awhile.
Personally, I have never seen the undiagnosed people cause any disruption. Rather some sort of bullying that comes from the other group. It's really weird. Like having PTSD is somewhat exclusive and people who are unsure yet of their diagnosis should not be allowed to add to the conversation.
I think some of that is symptoms, too. People struggle with diagnosis, and it comes out sometimes in really defensive ways.
But also, there have been members periodically who aren't suffering from PTSD, who come here and end up becoming the center of a lot of conflict among the other members - sometimes because of what their disorder actually is, and how it makes them behave. Sometimes because they are lying in order to troll the site. After you've been here for a few years, you'll probably see one or two like that. Those are the non-PTSD people that end up frustrating other members enough to make them feel justified in jumping on anyone who isn't dealing with PTSD.
