I don't know, since I don't have a mental ilness nor I'm a doctor.

The Blood Canvas.

Idk, I'm trying to look for one with anxiety, panic attacks. Something like that

Psychosis and Computer Vision Syndrome are among my favourites for mental illness stories.

The Blood Canvas.

Psychosis is probably my favorite creepypasta, period. Only one I think I've reread more is On the Bus.

From the Mental Illness category, Tulpa also comes immediately to mind, though I dunno if I'd call it "accurate" to anything, lol.

(Bonus answer: Cackling.)

For the best one, I tried to think of a novel one, but in the end, I think all three of the choices other people gave are good. "Psychosis" is a very well-written story about someone's descent into madness even though it's not on the wiki right now due to licensing reasons. "The Blood Canvas" has amazing and imaginative descriptions which contribute to an ultimately grounded story. "Computer Vision Syndrome" is also an interesting story which combines a bunch of different aspects of creepypastas into a single cohesive narrative.

As for accurate stories, "The Blood Canvas" seems like a story which is relatively accurate provided you understand the metaphor. That said, I feel like there were at least a few stories I read which were just describing life with a specific mental illness. Those might be the closest to "most accurate" even though I don't remember the titles. Keep in mind that writers might not necessarily have the mental illnesses they are writing about.

(I also wrote two stories that might be accurate to mental illness, specifically "ICU Delirium" and "Something Weird Happens When I Use the Internet", but they're nowhere near as good as the other three and may not be accurate.)

Speaking of Psychosis being removed, I recently came across an interesting thread someone posted a while back on the legacy forum. While I haven't verified any of the information therein, if OP is being truthful (and I see little reason to doubt they are), it seems like nobody even attempted to contact Matt Dymerski at any point to ask if he was fine with the pasta being on here... And based on his tone, it seems like he'd have probably been chill with it...? I dunno, I'm likely missing some important bits of context, but I can't help but find the decision a bit baffling in light of that. (Though I will admit I'm biased, lol.)

@LOLSKELETONS I may be guilty of not having read that post entirely correctly before I made that response back in 2022. Oh well. Thanks at least for bringing it up again.

HopelessNightOwl was the admin who deleted the story in 2019, so I'll ask him what exactly it was that prompted him to make said deletion; hopefully I can get a more exact response. It might have been done as a safety precaution due to questions over the story's license, or a lack of evidence that the story was up with Matt Dymerski's permission. If I need to, I'll send Matt a message through the website mentioned in that original forum post and ask him personally if we can have the story up, because I think that we should if we can.

That's why I feel like I'm missing some context here. I really can't see why Owl would specifically single out Dymerski's stories based on what information I do have.
