Mental illnesses like schizophrenia, depression, and bipolar disorder are legitimate medical conditions, not character flaws. They are caused by genetic and biological factors and can be effectively treated. However, stigma and lack of understanding prevent many from seeking help. Myths that those with mental illnesses are dangerous or that conditions like depression are simply weakness perpetuate social stigma. In reality, around 1 in 4 people will experience a mental health problem in their lifetime, and conditions like depression result in significant economic costs due to lost productivity. Increased education is needed to reduce the stigma around mental illnesses.
