The COVID-19 pandemic outbreak had many important consequences for human beings worldwide; this includes the mental health of everyone. The global covid-19 pandemic has had a significant effect on students' mental health and general wellbeing. As the world moves beyond the pandemic, it is essential to address the lingering mental health needs of Nigerian students. This paper explores the mental health challenges faced by students post-covid-19, including anxiety, depression, and trauma. We examine the factors contributing to these challenges, such as social isolation, academic pressure, and uncertainty about the future. This research paper analyzes the manner in which COVID-19 has affected Nigeria’s psychological wellness, particularly that of students. The limitations put in place to stop the virus's spread, like lockdowns and social distancing policies, have impacted people's daily routines and social support networks, leading to unanticipated changes that have brought about a lot of challenges and anxiety, stress, and depression.
