All sorts of bodily diseases are produced by half-used minds.

George Bernard Shaw

Both fear and anxiety send signals through the body that prepare all systems for possible danger. Hormones, such as adrenaline and catecholamine, are released in what is known as the "fight or flight" response. The sudden increase in hormone levels speeds up the heart and increases the amount of blood being pumped. At the same time, the muscles tighten, increasing the individual's ability to fight or flee from danger. The intensity of these physiological responses varies according to the seriousness of the event or thought that sparked the emotion, the strength of the individual's fear or anxiety, and his or her previous experience and genetic makeup.

While both fear and anxiety can provoke an arousal response, their other effects diverge. Very intense fear sometimes serves to "freeze" the body to protect it from harm, causing little or no change in heart rate and blocking the impulse to move. In anxiety, the physical changes caused by arousal lead to a second stage marked by thought patterns such as worry, dread, and mental replays of anxiety-arousing events.

Thousands of scientific studies over the past several years show that high blood pressure, ulcers, migraine headaches, strokes, alcoholism, depression, anger, fatigue, drug addiction and many other medical conditions are often due to the long-term effects of stress.

Depressed people will seem sad, or "down," or may be unable to enjoy their normal activities. They may have no appetite and lose weight (although some people eat more and gain weight when depressed). They may sleep too much or too little, have difficulty going to sleep, sleep restlessly, or awaken very early in the morning. They may speak of feeling guilty, worthless, or hopeless; they may lack energy or be jumpy and agitated. They may think about killing themselves and may even make a suicide attempt. Some depressed people have delusions (false, fixed ideas) about poverty, sickness, or sinfulness that are related to their depression. Often feelings of depression are worse at a particular time of day, for instance, every morning or every evening.

Not everyone who is depressed has all depression's symptoms, but everyone who is depressed has at least some of them, co-existing, on most days. Depression can range in intensity from mild to severe. Depression can co-occur with other medical disorders such as cancer, heart disease, stroke, Parkinson's disease, Alzheimer's disease, and diabetes. In such cases, the depression is often overlooked and is not treated. If the depression is recognized and treated, a person's quality of life can be greatly improved.

Symptoms of this disorder are often mild, and do not interfere with work or social situations. If symptoms are severe, however, they can disrupt daily activities. Because people with generalized anxiety disorder often have another physical or emotional disorder, such as depression, there has been much learned debate as to whether anxiety disorder exists on its own. But recent studies indicate that there really is such a disorder, and that it can be helped by diagnosis and treatment. The symptoms of generalized anxiety disorder usually begin in youth and may go untreated for decades. However, they tend to diminish with age. One study found that only 3 percent of cases of generalized anxiety disorder began in those 65 and over. The problem is more common among women than men and often runs in families.

Many people with anxiety disorders benefit from joining a self-help group and sharing their problems and achievements with others. Talking with trusted friends or a trusted member of the clergy can also be very helpful, although not a substitute for mental health care. Participating in an Internet chat room may also be of value in sharing concerns and decreasing a sense of isolation, but any advice received should be viewed with caution.

The family is of great importance in the recovery of a person with an anxiety disorder. Ideally, the family should be supportive without helping to perpetuate the person's symptoms. If the family tends to trivialize the disorder or demand improvement without treatment, the affected person will suffer. You may wish to show this booklet to your family and enlist their help as educated allies in your fight against your anxiety disorder.
