Yes! Exactly this. If I'm lying awake running over an argument in fandom in my head... it's not the dolls or the stories or whatever. And it doesn't actually matter that someone is being wrong on the internet, even if they are being wrong about me personally, so if it's distressing me that much, there's something else going on.
The hardest thing is learning that just because a thread is updated or something, I don't need to go back and look and answer. But having someone supportive to teach you when to step back is very helpful when the depression gets in the way, and
biipagan seems to need that help right now.
