The Dangers of Self-Diagnosing Mental Illness: What You Need to Know

Updated: Apr 19

Imagine scrolling through social media and stumbling upon a post that perfectly describes your recent struggles with anxiety or depression. The words resonate with you on a deep level, and suddenly, you begin to wonder if you've finally found the answer to what's been plaguing you. You become your own mental health detective, researching symptoms, reading online forums, and ultimately arriving at a self-diagnosis. But here's the question: is this self-diagnosis helping or harming you?

In this article, we delve into the dangers of self-diagnosing mental illness, shedding light on the risks and pitfalls of relying solely on online resources and personal interpretations. We explore the allure of self-diagnosis, the impact of unreliable online sources, the importance of seeking professional help, and the potential consequences of misdiagnosis. So, before you hit that "diagnose" button, let's unravel the truth behind self-diagnosis and understand why it's crucial to tread carefully when it comes to matters of mental health.

Why do we feel the need to self-diagnose


Self-diagnosis of mental illness has become increasingly preferable in recent years. There is more information than ever before on variants of mental illness, disorders and genetic conditions readily available online at the click of a button. Self-diagnosis of mental illness can take a long time through the NHS especially post-pandemic, Being able to get a doctor appointment in general has become more of a struggle, not to mention the various appointments required before diagnosis and waitlists for therapy post-diagnosis, so no wonder a lot of us are trying to skip some steps and speed up the process in trying to pursue our recovery.


The allure of self-diagnosis lies in the sense of control it offers. When faced with mental struggles, we naturally seek answers and explanations for our experiences. The internet provides a seemingly endless pool of information, ready to be explored and interpreted through our own filters, but how do we know what information is genuine and reliable?

The appeal of self-diagnosis extends beyond mere curiosity. It offers a sense of validation and relief, as finding a label for our symptoms gives them a tangible form. Suddenly, the jumble of emotions and thoughts can be neatly categorized under an umbrella term. It becomes a way to make sense of our own complexities, validate our struggles, and seek solace in knowing that others have gone through similar experiences.

Anxiety feeds off of two main components, the need for control and the fear of judgement from others. You can learn more about how these two factors create anxiety in our blog:

No Judgement

Self-diagnosis can also hold a certain level of comfort. It eliminates the need to confront the uncertainties and discomfort of facing a mental health professional. Instead, we can hide behind the anonymity of online resources and forums, where we feel safe. This illusion of control can be compelling, especially when faced with the daunting prospect of seeking professional help and potentially facing stigmatization or judgment.

It is crucial to recognize the limitations of self-diagnosis. While it may offer temporary relief and a sense of understanding, it often fails to provide the full picture. Online resources and forums, while valuable sources of support and information, lack the expertise and personal understanding that mental health professionals possess. They cannot accurately assess the nuances of individual experiences or provide the personalized guidance that is crucial for a comprehensive understanding of mental health.

The risks of self-diagnosing mental illness

What is Confirmation Bias: the tendency to interpret new evidence as confirmation of one's existing beliefs or theories.

Self-diagnosis runs the risk of confirmation bias. Once we latch onto a particular diagnosis, we tend to seek out information and experiences that support our beliefs, disregarding contradictory evidence. This tunnel vision can lead us down a path of misinterpretation, as we unintentionally amplify and fixate on certain symptoms while overlooking others that may be crucial in understanding our mental health.

The human mind is brilliant but it can also be tricked, often when self-diagnosing we may project symptoms onto ourselves, for instance, if a symptom is foot swelling; we may not be experiencing it right in this moment, but have done it three months ago. This could have been due to heavy exercise or poor footwear but instead, we may recall that and project it into the cause of what you are experiencing now.


Without the guidance of a trained professional, we may misinterpret our symptoms and incorrectly identify the root cause of our struggles. Mental health conditions often have overlapping symptoms, making it easy to mistake one illness for another. For example, feelings of sadness, fatigue, and loss of interest in activities can be signs of depression, but they can also be indicative of other conditions such as anxiety disorders or even medical issues like thyroid problems.

Coexisting Conditions

Mental illnesses can progress into 2 or even three conditions or disorders, this is most common with anxiety disorders. Misdiagnosing one could lead you to "self-treat" for the incorrect disorder, in turn making anything contributing to disorders worse. Mental illness can be extremely confusing and distressing, no person needs the stress of misinterpretation on top.

Self-diagnosis does not take into account the complexity and interconnectedness of mental health conditions. Many mental illnesses share common symptoms or can coexist in individuals, making it difficult for untrained individuals to accurately navigate these differences. This lack of comprehensive understanding can lead to inaccurate self-labelling and unnecessary distress.

Self-Medication and Treatment

Self-diagnosing mental illness also opens the door to self-medication, which can have grave consequences. Misidentifying a mental health condition and attempting to treat it without professional guidance can exacerbate symptoms or lead to further complications. It is crucial to remember that mental health treatment often involves a combination of therapy, medication, and lifestyle changes, all of which should be tailored to an individual's specific needs. By self-diagnosing and self-medicating, we risk overlooking effective treatment options and potentially worsening our mental health.

The impact of unreliable online resources

In today's digital age, information is at our fingertips, and a quick internet search can yield countless results on mental health conditions. While this accessibility can be beneficial, it also presents a significant challenge. The vast sea of online resources encompasses a wide range of quality, accuracy, and trustworthiness. Unfortunately, not all sources are created equal, and relying on unreliable information can have serious consequences.

One of the main risks of relying on unreliable online resources for self-diagnosing mental illness is the potential for misinterpretation or misrepresentation of symptoms. Mental health conditions can be complex, presenting with a variety of signs and symptoms that may overlap with other disorders. Without the expertise of a qualified professional to guide us, we may mistakenly conclude that we have a specific condition based on incomplete or inaccurate information.

Online resources lack the crucial element of individualization that is essential in mental health treatment. As mentioned earlier, effective treatment often involves a combination of therapy, medication, and lifestyle changes tailored to an individual's unique needs. Online resources cannot provide the personalized care and guidance necessary to develop an appropriate treatment plan. By relying solely on these resources, we risk disregarding potential treatment options that could significantly improve our mental well-being.

Another concern about relying on unreliable online resources is the potential reinforcement of stigmatizing beliefs or harmful stereotypes surrounding mental health. Some sources may perpetuate outdated or incorrect information, leading to misunderstandings and biases.

It's important to recognize that online resources should never replace the expertise and guidance of trained professionals. While the internet can be an invaluable tool for obtaining information, it should be used as a supplement, not a substitute, for seeking professional help. By relying on credible sources and consulting with mental health professionals, we can navigate the complexities of mental health with caution and make informed decisions about our well-being.

The potential consequences of misdiagnosis

The potential consequences of misdiagnosis can be severe. When individuals attempt to self-diagnose their mental health conditions without the guidance of trained professionals, they run the risk of misunderstanding and misinterpreting their symptoms. This can lead to inaccurate conclusions about their own mental state, potentially exacerbating their condition or delaying proper treatment.

The individual

For the individual, it means grappling with the wrong information and potentially pursuing treatments or interventions that are not suitable for their actual condition. This can result in:

  • Prolonged suffering, as their true needs remain unaddressed.

  • Sense of frustration

  • Hopelessness

  • Further deterioration of their mental well-being


When someone is misdiagnosed and undergoes inappropriate treatments or fails to receive the necessary support, it can:

  • Strain their relationships with family, friends, and colleagues.

  • Misunderstandings and conflicts may arise

  • A strain on social connections and support systems

The Mental Health Field

Additionally, the potential consequences of misdiagnosis can impact the mental health field as a whole. It can:

  • Perpetuate misconceptions and stigma surrounding mental illness

  • Create barriers for those who genuinely need help to seek it.

  • Confuse and misinform others

It is crucial to remember that mental health is complex and multifaceted. Self-diagnosing based on internet resources or personal experiences alone can overlook important factors and professional insights. By turning to trained professionals, we can receive accurate assessments and individualized treatment plans that consider the nuances of our unique situations. Seeking expert guidance ensures that we are on the right path towards mental well-being and prevents potential harm or delays in receiving the appropriate care.

As the saying goes, "To see the light at the end of the tunnel, seek guidance from those who understand the complexities of the darkness."
