Worrying is part of human nature. As humans, we are hard-wired to scan our environments for potential threats. While some worry is good and adaptive, anxiety disorders can manifest. Approximately 9% of U.S. adults are diagnosed with Generalized Anxiety Disorder (GAD). A person with GAD worries about all sorts of things (e.g., relationships, work, finances, etc.) and finds the worry excessive and difficult to control. Others may experience anxiety as a specific phobia, such as fear of flying. Individuals can also have social anxiety where they fear judgment and rejection from others. Still others may have excessive worry about different physical symptoms and the potential for illness. In some cases, the anxiety can come in the form of a panic attack. These are short periods characterized by an overwhelming fear of dying and physiological sensations, such as increased heart rate, shakiness, difficulty breathing, and nausea.
