Anxiety and depression are two of the most common mental health conditions. Many people use these terms interchangeably, but they are not the same. While they share some similarities, they are distinct disorders with unique symptoms, causes, and treatments. Understanding the differences between anxiety and depression is crucial for proper diagnosis and effective treatment. This article will explore the key differences and similarities between anxiety and depression, helping you better understand these conditions.
What Is Anxiety
Anxiety is a natural response to stress. It is a feeling of fear or worry about what is to come. For example, feeling anxious before a big test or a job interview is normal. However, when anxiety becomes excessive, persistent, and interferes with daily life, it may be classified as an anxiety disorder.

Panic Disorder: Characterized by recurrent panic attacks, which are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something terrible is going to happen.
Social Anxiety Disorder: Characterized by overwhelming anxiety and excessive self-consciousness in everyday social situations.
Specific Phobias: Characterized by an intense fear of a specific object or situation, such as heights or flying.
