And worrying about them tends to exaggerate their effects. There are several different types of anxiety disorders. People with GAD often seem unable to relax or fall asleep and may experience lightheadedness, shortness of breath, nausea, trembling, muscle tension, headaches, irritability, or sweating. PD can become disabling when people avoid situations they fear may bring on an attack. Panic attack symptoms include rapid pulse, chest pains, shortness of breath, dizziness, nausea, numbness, trembling, and a fear of going crazy or dying.
Panic disorder is probably the best studied and understood of the anxiety disorders.
Agoraphobia , the most disabling anxiety disorder, is diagnosed when panic attacks cause people to increasingly refrain from normal activities. Unlike shyness, those with SP can feel at ease around others, yet particular situations, like walking down an aisle, cause intense anxiety. SP disrupts relationships and careers as sufferers avoid certain situations. Compulsive activities consume an hour or more each day and interfere with daily life. Anniversaries of the incident can be difficult and ordinary events can trigger flashbacks or intrusive images.
