Mental health is a crucial aspect of our overall well-being, yet it remains one of the most misunderstood and stigmatized areas of health. Understanding the different types of mental illnesses is essential for recognizing symptoms, seeking appropriate treatment, and reducing the stigma associated with these conditions. In this article, we will explore the various categories of mental illnesses, their symptoms, and how they impact individuals’ lives.
What Constitutes a Mental Illness?
Defining Mental Illness
A mental illness, also known as a mental health disorder, is a condition that affects a person’s thinking, feeling, behavior, or mood.
