I've seen a couple people reblog with these sorts of worries, and this is my advice: consider and think on the idea. What if you're wrong? What would change?
I'm formally diagnosed with DID, I have been for a long while now, and I still find it healthy and helpful to ask myself that. If I was wrong, if my psychs were wrong, what would change?
My experiences wouldn't change, because my experiences are not constrained to a diagnosis. Maybe the framing around them would change, parts as they exist in DID are different from parts of folks with integrated self. But both are parts nonetheless, and I would still work with my therapist to figure out what purposes my parts (in any sense) hold.
However, I'm not someone who's actively online "as a system." This is a side blog, most people in my life do not know about my DID. I wouldn't have to tell anyone I was wrong.
I do think though, that in pondering this question, if you come to the conclusion that your relationships would need to MAJORLY change with others, or even that being wrong would end your relationships with others, that that's a red flag in and of itself. Whether that means you need to surround yourself with different people, whether that means you're putting too much weight into this identity and the ways you use that identity online, there's a lot of ways folks, including folks who do have dissociated parts of self, can form unhealthy relationships online by basing them too heavily in this one aspect of themselves. I would ask you to question your behavior online if you feel you could be cut off from your relationships by being wrong or changing your mind. I also suggest asking yourself if you would act the same way offline.
This all applies tenfold if you're underage, or even 18/19/20. Identity confusion is actually a normal and incredibly important part of development for many in their teens. Your teens are when you've basically just started becoming a full person in the eyes of society, it's when your brain is starting to define itself by its own terms rather than defining it by the ways others have labeled you, and it's important to use that time to discover who you are. Changing contexts (going into high school, or moving out of your parents house) can trigger identity crises as well.
As I said in my original post, things will still be here when you get back, if you're wrong or if you're right. And if you discovered that you don't have dissociated parts of self/DID/OSDD, but something you found in these communities was helpful, that's good! You can keep that! It may be helpful to look into parts work designed for non-dissociative folks, like IFS.
As someone else also pointed out on this post, it's been quite the year. A lot of folks are having identity and dissociation issues from being in quarantine. Especially school age youth who would normally depend on interacting with others their age to develop more, get a sense of what's normal, etc. I would highly question yourself and the people around you if you find yourself surrounded by other folks claiming DID/OSDD TBH. We're more common than some think, but not THAT common.
