The avoidance behaviors associated with agoraphobia can greatly restrict a person’s life. People with agoraphobia often develop groups of feared situations that are related. For example, many people with agoraphobia become extremely upset and uncomfortable in areas where there are many people in a confined space. This fear may limit them from standing in line at a store, going to a movie theater, or traveling on an airplane. Other commonly feared situations for people with agoraphobia include forms of travel, being alone, and open spaces. These fears may result in an inability to even leave their homes.
Some research suggests that people who have panic disorder might be very sensitive to sensory experiences (such as sunlight, smells and changes in the weather), but there's not enough evidence yet to say for sure. Also it's not clear whether having a high level of sensitivity to these sorts of things is something that might cause you to develop panic disorder, or whether it may be an effect of having it.
So how do you know if your anxiety is “normal” or “excessive?” It’s normal to be worried about an upcoming test or wondering how you are going to cope financially when you unexpectedly find out you need major repairs done to your house. If you are suffering from the type of excessive worry that accompanies Generalized Anxiety Disorder, you may see a report on the local news about a new health scare in a different country and stay awake at night worrying about you or your family being affected, even though risks are minimal at best. You will likely spend the next few days and weeks in a constant state of worry about the well-being of your family and experience anxiety that is debilitating, intrusive, excessive, and persistent.
Although your gut response might be to leave the stressful situation immediately, don’t. “Let your anxiety level come down,” advises Carmin. Then you can decide if you want to leave or if there's a way to get back to whatever you were doing when the anxiety attack started. Staying in the moment will help you overcome anxiety, but it’s hard to do this at first.
Hyperventilation syndrome may occur when a person breathes from the chest, which can lead to overbreathing (exhaling excessive carbon dioxide in relation to the amount of oxygen in one's bloodstream). Hyperventilation syndrome can cause respiratory alkalosis and hypocapnia. This syndrome often involves prominent mouth breathing as well. This causes a cluster of symptoms, including rapid heart beat, dizziness, and lightheadedness, which can trigger panic attacks.
Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
