The article reviews the mental health challenges faced by lesbian, gay, and bisexual (LGB) individuals, highlighting the concept of minority stress as a key factor. It presents evidence that LGB populations have higher rates of mental disorders, such as depression and anxiety, compared to heterosexuals. Central to this disparity is the minority stress model, which identifies stigma, prejudice, and discrimination as significant contributors to psychological distress. The author also reflects on the historical context of homosexuality’s classification as a mental disorder, asserting that mental health issues in LGB individuals arise from societal stigma rather than their sexual orientation. The article calls for more research and supportive policies to address these unique stressors and improve mental health outcomes for LGB populations.
