Discovered in December 2019, Coronavirus (Covid-19) is an infectious disease that has spread rapidly around the world. The World Health Organization (WHO) declared Covid-19 a pandemic in March 2020. The pandemic has increased the occurrence of mental health problems including depression, stress, and anxiety. This research used real-life Tweets collected related to Covid-19 from March 2020 until October 2021. The objective is to analyze Tweets from the US, UK, and India to discover what topics people are discussing about Covid-19's impact on mental health. The theme for the US was related to government and politics, some dominant users in the group are news accounts and people who have occupations such as journalists, hosts, and presenters. The UK’s theme focused on friends and family relations, and it showed the caring for the public safety, resulting in doctors and medical workers as dominant users. India is focusing on mental health and education. However, some important users identified are the majority news related accounts and people related to politics.
