Mental illness affects millions of people worldwide, but many don't seek help due to stigma, access to care, or misconceptions. However, people with mental illness can live full and rewarding lives with proper support and treatment. Mental illnesses are caused by chemical imbalances in the brain and can trigger a range of symptoms, including depression, anxiety, mood swings, and hallucinations. People may be afraid to seek help due to concerns about their job or relationships, but employees are protected by laws that safeguard privacy and prevent discrimination.
