Mental illnesses are illnesses that cause changes in emotion, thought, or behavior (or a combination of these). Distress and/or issues functioning in social, job, or family activities are common symptoms of mental diseases. Emotions, thinking, communication, learning, resilience, and self-esteem are all built on a foundation of mental health. Relationships, personal and emotional well-being, and contributing to the community or society all require good mental health. Many persons who suffer from mental illnesses are apprehensive about discussing their condition. Mental disease, on the other hand, is not something to be embarrassed of! It is, like heart disease, a medical problem. Mental illnesses, on the other hand, are treatable. Treatments are available to help people successfully manage mental health disorders, and our understanding of how the human brain works is constantly expanding.
