Mental health has become an important global health issue, especially with the advent of COVID19 pandemic. This has been primarily driven by diverse factors, including, job loss, pay cut, loss of loved ones, domestic violence, social isolation, among others. Alongside resource constraints, societal stigma is another key challenge being faced by healthcare practitioners and care givers around the world in responding to mental health issues. With the pandemic having pushed many people across geographies and across social strata into some form of a mental health challenge (either directly or indirectly), we attempt to uncover, if there have been any remarkable shift in the way societies perceive mental health. By performing exploratory data analysis on #mentalhealth network on Twitter, we attempt to track the evolution of mental health narratives during the course of the pandemic, alongside identifying key actors who are driving these narratives. We expect the outcome to be beneficial for various stakeholders, including policymakers, public health experts, social scientists, mental health practitioners, and epidemiologists, especially in terms of understanding the efficacy of social media as a means for both understanding and managing mental health, given the stretched budget devoted to tackle mental health.
