Depression: Understanding, Symptoms and Finding Support

Depression is a serious but treatable medical condition that affects how you feel, think and handle daily activities. In India, the World Health Organization estimates that 56 million people suffer from depression — yet fewer than 10% receive treatment, largely due to stigma and lack of accessible care. Recognising the signs of depression early — persistent low mood, loss of motivation, fatigue, or withdrawal from things you used to enjoy — is the first step toward getting support.

What Is Depression?

Clinical depression (major depressive disorder) is characterised by a persistently low mood or loss of interest in activities, lasting at least two weeks. It is not simply sadness or "feeling blue" — it is a biological condition involving changes in brain chemistry, hormone levels and neural circuitry.

Types of Depression People Often Miss

Not all depression looks the same, and several presentations are commonly searched because they are so frequently overlooked.

Smiling depression is a term that describes people who appear content — even happy — to the outside world while experiencing a major depressive episode internally. They go to work, laugh at dinner, post on Instagram. The disconnect between the external performance and the internal experience is exhausting, and it often prevents the person from seeking help because "I don't look depressed." Searches for smiling depression signs have risen sharply as awareness grows.

Quiet depression is similar — it describes depression that is inward-facing rather than visibly distressing. There are no dramatic breakdowns. Just a steady withdrawal from things that used to matter, a flatness where emotions used to be, and a persistent sense of going through the motions. People with quiet depression often describe it as "not being sad exactly, just not really being anything."

Functional depression (sometimes called high-functioning depression or dysthymia) involves a persistently low mood lasting more than two years, which is mild enough to allow daily functioning but chronically depleting. Many people live with functional depression for years without knowing it has a name, attributing their persistent fatigue, low motivation and lack of joy to personality rather than a treatable condition.

Symptoms of Depression

Emotional: Persistent sadness, hopelessness, emptiness, loss of interest (anhedonia), feelings of worthlessness, thoughts of death or suicide.

Physical: Fatigue and low energy (one of the most commonly searched symptoms — depression and fatigue is extremely common), changes in sleep (insomnia or oversleeping), appetite changes (weight loss or gain), difficulty concentrating, slowed movement or speech.

Depression in India: A Hidden Crisis

In India, depression is often under-recognised because it manifests differently — more commonly as physical symptoms like chronic pain, fatigue and digestive problems rather than the emotional symptoms more recognised in Western contexts. Women are twice as likely as men to be diagnosed, though men are less likely to seek help. Academic pressure, family conflict, unemployment and the aftermath of the COVID-19 pandemic have all contributed to rising depression rates.

The Gut-Brain Connection and Depression

An increasingly important and trending area of mental health research is the gut-brain connection. The gut is sometimes called the "second brain" — it contains around 100 million neurons and produces approximately 90% of the body's serotonin. Studies now show that gut microbiome health has a measurable influence on mood, and that people with depression often have different gut bacteria profiles compared to those without. While this does not mean you should treat depression purely through diet, it does mean that consistent sleep, regular physical activity, a varied diet with plenty of fibre, and reducing ultra-processed food intake all have a direct impact on the neurochemistry that influences mood — not just as general wellness advice, but as part of a biologically informed approach to overcoming depression naturally alongside professional support.

The chatbot guides you through thought records to challenge hopelessness and low self-worth.

For those wanting to manage depression at home in India without immediate access to a therapist, Mentis provides structured CBT support available any time of day — free to start on iOS and Android.

Frequently Asked Questions

What is the difference between sadness and depression?
Sadness is a normal emotion that passes. Depression is a persistent condition lasting at least two weeks, significantly impairing daily functioning, and often accompanied by physical symptoms and hopelessness rather than situational sadness.
What is smiling depression, and how do I know if I have it?
Smiling depression describes people who appear happy or functional to others while privately experiencing a depressive episode. Key signs: you perform wellness publicly but feel empty or hopeless privately; you wake early with dread; activities that used to bring joy feel hollow; you are exhausted by the effort of appearing fine. If this sounds familiar, please speak to a mental health professional — the fact that others cannot see your struggle does not make it less real or less treatable.
What is quiet depression or functional depression?
Quiet depression refers to a low-profile depressive experience — no dramatic breakdowns, just a chronic flatness, withdrawal from things that used to matter, and going through the motions without feeling present. Functional depression (dysthymia) is a clinical diagnosis describing persistent low mood lasting two or more years. Both are treatable with CBT and, in some cases, medication.
Is depression a sign of weakness?
Absolutely not. Depression is a medical condition with biological, psychological and social causes. No more a sign of weakness than diabetes or hypertension.
How is depression treated in India?
CBT, medication and lifestyle interventions are all available in India. Access is improving through digital platforms like Mentis that bring CBT to anyone with a smartphone.
Can an app really help with depression?
For mild to moderate depression, digital CBT apps like Mentis have been shown to produce meaningful improvements. They are most effective as a complement to professional care for moderate-severe depression.
What is behavioural activation?
Behavioural activation is a CBT technique specifically for depression. It involves scheduling and completing meaningful activities even when motivation is low. It breaks the inactivity cycle that maintains depression.
