Anxiety is more than simply feeling nervous. When a person has an anxiety disorder they have intense tension, have frequent worries, and they can have physical health issues, such as an increase in blood pressure. They can experience dizziness, an increase in heart rate, sweating, and shaking or trembling. A person who is anxious has intrusive thoughts – even if they try to distract themselves, their mind goes back to topics that they apparently cannot easily shake off. They tend to avoid places and situations out of concern that ‘something bad’ may happen. Sometimes the symptoms of anxiety are nearly constant, but often the anxiety is ‘quiet’ at times – flaring up when the person comes in contact with some sort of trigger.
