Anxiety is a complicated subject, and can be interpreted differently depending on the sufferer's knowledge of certain areas of neuroscience and psychology. I've been lucky to study anxiety deeply enough that it no longer has control over me. As a sidenote, anxiety comes from the German word for anger, and is the result of unaddressed internal dialogue within the sufferer, closely related to cognitive dissonance, or witnessing too many paradoxes throughout the day. Avoid paradoxical thinking - it gets in the way of the task at hand, which is usually something mundane like getting in a lift, or even walking the dog.
