Verified step by step guidance

1. Step 1: Understand the definition of anxiety disorders. Anxiety disorders are a group of mental health diagnoses that lead to excessive nervousness, fear, apprehension, and worry.
2. Step 2: Review the examples of anxiety disorders listed: Panic Disorder, Generalized Anxiety Disorder, and Obsessive-Compulsive Disorder (OCD). These are all recognized as anxiety disorders in the DSM-5, although OCD is now classified separately under obsessive-compulsive and related disorders.

4. Step 4: Recognize that the question asks for the exception, meaning the disorder that is NOT an anxiety disorder among the options provided.
5. Step 5: Conclude that Major Depressive Disorder is the correct answer because it is classified as a mood disorder, not an anxiety disorder.
