TikToks Mental Health Rabbit Hole: Support, Self-Diagnosis, and the Darker Side of the Comment Section
TikToks Mental Health Rabbit Hole: Support, Self-Diagnosis, and the Darker Side of the Comment Section
Scroll through TikTok for a few minutes and you will find them: videos of creators describing their ADHD symptoms, their anxiety spirals, their depression. The comment sections below are often just as revealing as the videos themselves. “Wait, this is me,” one user writes. “I thought I was the only one,” says another. But scroll a little further and you will find something else: debates about whether self-diagnosis is valid, claims that doctors dont listen, and occasionally, dangerous misinformation.
A new study led by Dr. Katie Saunders from Keele Universitys School of Medicine takes a close look at whats actually happening in those comment sections. Published in the Journal of Social Media Research, the paper reveals a complex picture — one where genuine support and connection coexist with misinformation and real risks for vulnerable users.
What the Researchers Did
Saunders, who conducted the study as part of her Ph.D. at Birmingham City University, didnt rely on surveys or interviews. Instead, she went straight to the source. Using TikToks Application Programming Interface (API), her team analyzed mental health-related content posted during three separate periods: 2021, 2022, and 2023.
They focused on videos tagged with hashtags like #MentalHealth, #Depression, #Anxiety, #SelfDiagnosis, and #ADHD — and then turned their attention to the comments beneath those videos. What they found was not a single narrative but six distinct themes that capture how users engage with this content.
Six Ways People Respond
The first theme is the most heartening: users offering support and empathy. “Youre not alone.” “Thank you for sharing this.” These comments create a sense of community that many people, especially those struggling in silence, may not find elsewhere.
The second theme is relatable content — users comparing the creators experience to their own. “This explains my whole life,” one comment might read. Its a form of validation that can be powerful, especially for conditions like ADHD that are often misunderstood.
Then come the cries for help. Some are indirect — vague comments hinting at distress. Others are direct. These comments reveal that for some users, TikTok isnt just entertainment; its a lifeline theyre grasping at in public.
The final three themes all revolve around self-diagnosis. Some users affirm the practice, arguing that formal diagnosis is inaccessible, expensive, or simply not worth the hassle. Others explain why they chose not to self-diagnose, citing a desire for professional clarity. And a third group pushes back against self-diagnosis altogether, arguing that it trivializes serious conditions or spreads misinformation.
Why People Self-Diagnose
The study sheds light on a question that often puzzles clinicians: why do so many people turn to TikTok instead of a doctor? The answers are not surprising, but they are sobering. Mist rust of healthcare professionals. Financial barriers. Long wait times. For some, the comment section feels more accessible than the clinic.
As Saunders puts it, “The comments also reveal insights into why more people choose to self-diagnose, such as mistrust of health care professionals or financial reasons.”
Thats not to say self-diagnosis is inherently bad. For some, its a first step toward seeking help. For others, its a way to find community when formal systems have failed them. But the researchers warn that it can also lead people down rabbit holes of misinformation, especially when content is designed for engagement rather than accuracy.
The Darker Side
Saunders doesnt mince words about the risks. “Unfortunately, it also highlights the darker side of social media, where people may use these platforms to spread misinformation purely for engagement or financial gain, or to promote self-harm and suicidal ideation,” she says.
The study found commenters sharing ideas about self-harm and suicide — content that could be deeply harmful to vulnerable users. And its not just in the videos themselves. “People are also actively having these conversations in comment sections,” Saunders notes.
Thats a crucial point. Moderation efforts often focus on the videos, but the comment sections are where some of the most meaningful — and most dangerous — interactions happen.
What Can Be Done?
The researchers are calling on tech companies to step up. They argue that platforms like TikTok need appropriate safeguards and educational measures to protect users, especially those who are already struggling.
But Saunders also sees potential. “Social media is such an ingrained part of peoples lives, and these findings show that if used effectively, it can actually be utilized as a means to gain social support and interact with like-minded people,” she says.
Thats the tension at the heart of this study. TikTok can be a place where someone finally feels seen — or a place where they fall deeper into a spiral. The difference often comes down to the quality of the information and the tone of the community.
A First Step, Not a Final Answer
Saunders hopes this research is just the beginning. “I hope that this research is the first step in understanding these platforms better so that users can gain the most benefits from using them,” she says. She also wants to see future projects explore why people avoid formal support and how online communities could be used to promote better well-being.
For now, the takeaway is clear: the conversation about mental health on TikTok is not going away. Its happening in videos, in comments, in debates about diagnosis and identity. And if we want to make that conversation safer and more helpful, we need to understand it — not dismiss it.
So next time you scroll past a mental health video, take a moment to read the comments. You might see support, you might see misinformation, and you might see someone asking for help. The question is: what should we do about it?
