The silent impact: How COVID-19 affected mental health globally

When the pandemic hit, the world focused on physical health; flattening the curve, increasing ICU beds, securing vaccines. But while the virus attacked lungs and immunity, it also quietly infiltrated our minds. The psychological toll of COVID-19 has been immense, yet much of it remains unseen, unspoken, and under-addressed.Each nation experienced its own kind of lockdowns, losses, and uncertainty. But across continents, there was one common thread: a silent mental health crisis playing itself out behind closed doors. The pressures of solitude, pain of loss, economic uncertainty, and fear of the unknown were a recipe for emotional stress.In countries like India, where extended family and social gatherings form the fabric of daily life, sudden isolation led to deep emotional disconnection. For many living in multi-generational homes, the fear of infecting vulnerable elders caused lingering anxiety. Elsewhere, in cities across Europe or North America, living alone became a double-edged sword, offering safety from the virus but amplifying loneliness.Anxiety, depression, insomnia, and burnout surged quietly, globally, and persistently. A 2022 WHO report estimated that the global prevalence of anxiety and depression increased by over 25% during the pandemic’s first year alone. That number only begins to scratch the surface. Many who needed help didn’t seek it. Some didn’t recognize what they were feeling. Others feared the stigma.Mental health was tested not just by the virus, but by the silence around it. People grieved loved ones they couldn’t say goodbye to, lost jobs they built their lives around, missed milestones they’d dreamed of. The parents overnight turned into teachers. Healthcare professionals strained themselves to the limit. Students lost the precious years of social development. The record continues.And yet, amid all this, we would constantly remind ourselves to be grateful. Grateful we lived. Grateful others were worse off. But gratitude and sorrow don't have to be mutually exclusive. You can be thankful and still wounded. That's what makes this emotional damage so confusing.For many, the pandemic didn’t cause mental health struggles it magnified what was already there. Pre-existing anxiety worsened. Past trauma resurfaced. Coping mechanisms, like alcohol or overworking, quietly spiraled into addiction. Even those who appeared fine on the outside were often managing an invisible storm within.One of the hardest-hit groups? The youth. Teens and young adults who are already navigating identity, relationships, and career pressure, were suddenly cut off from the very social systems that helped them grow. Online classes, canceled exams, and uncertainty about the future created a unique kind of emotional whiplash.In India, mental health services were overwhelmed, especially in urban centers. But rural areas, where awareness and access were already limited, faced an even greater challenge. The digital divide became not just an educational issue, but a mental health barrier too.Here’s how to address these things:First, we must acknowledge that healing from the pandemic isn’t just about physical recovery but it’s also emotional. We need global and local mental health systems that are responsive, affordable, and stigma-free. Governments, employers, schools, and families all have a role to play.Second, we must normalize asking for help. Therapy isn’t a sign of weakness. It is a step toward understanding. Whether you’re dealing with anxiety, fatigue, or just feeling “off,” it matters. You matter. This approach goes beyond diagnosis we create compassionate, culturally aware support that helps people find their footing again.The pandemic may have been global, but healing starts one mind at a time. Whether you're still carrying the weight of those years or just beginning to unpack them, know this: you're not alone, and recovery is possible.(Dr. Tonmoy Sharma, Psychiatrist Founder and CEO, Merlin Health)
