Anxiety Disorders — What Is Normal?

Psychologist Douglas Mennin, PhD, discusses stress and anxiety and when to become concerned that you might have an anxiety disorder. What's the difference between stress and anxiety? Stress can come from any situation or thought that makes you feel frustrated, angry, nervous, worried, or even anxious. Anxiety is a reaction to the stress, a feeling of apprehension or fear. You can feel anxious without having an anxiety disorder. And if you’re facing real danger or a realistic fear, you’re not usually considered to be in a state of anxiety.
