Anxiety is one of the most common mental health concerns I see in my practice. But knowing how to diagnose anxiety and when anxious feelings have crossed the line into a diagnosable anxiety disorder is not always clear.

In this article, I explain how anxiety is diagnosed, who can diagnose anxiety, and the steps mental health professionals take to distinguish everyday stress from an anxiety disorder.
