In recent years, social media has become an integral part of our daily lives. While it offers numerous benefits, such as connecting people and providing a platform for self-expression, it also has a darker side. This paper aims to explore the impact of social media on mental health, with a specific focus on the effects of cyberbullying, social comparison, and online harassment. We will also discuss the consequences of these phenomena on individuals, particularly young people, and provide recommendations for mitigating their negative effects.
