FEAR & FUBIA
A phobia is an excessive and irrational fear reaction. If you have a phobia, you may experience a deep sense of dread or panic when you encounter the source of your fear. The fear can be of a certain place, situation, or object. Unlike general anxiety disorders, a phobia is usually connected to something specific.
The impact of a phobia can range from annoying to severely disabling. People with phobias often realize their fear is irrational, but they’re unable to do anything about it. Such fears can interfere with work, school, and personal relationships.
An estimated 19 million Americans have a phobia that causes difficulty in some area of their lives. Seek the help of your doctor if you have a fear that prevents you from leading your fullest life.

Causes
Genetic and environmental factors can cause phobias. Children who have a close relative with an anxiety disorder are at risk of developing a phobia. Distressing events, such as nearly drowning, can bring on a phobia. Exposure to confined spaces, extreme heights, and animal or insect bites can all be sources of phobias.
People with ongoing medical conditions or health concerns often have phobias. There’s a high incidence of people developing phobias after traumatic brain injuries. Substance abuse and depression are also connected to phobias.
Phobias have different symptoms from serious mental illnesses such as schizophrenia. In schizophrenia, people have visual and auditory hallucinations, delusions, paranoia, negative symptoms such as anhedonia, and disorganized symptoms. Phobias may be irrational, but people with phobias do not fail reality testing.
Agoraphobia
Agoraphobia is a fear of places or situations that you can’t escape from. The word itself refers to “fear of open spaces.” People with agoraphobia fear being in large crowds or trapped outside the home. They often avoid social situations altogether and stay inside their homes.
Many people with agoraphobia fear they may have a panic attack in a place where they can’t escape. Those with chronic health problems may fear they will have a medical emergency in a public area or where no help is available.
Social phobia
Social phobia is also referred to as social anxiety disorder. It’s extreme worry about social situations and it can lead to self-isolation. A social phobia can be so severe that the simplest interactions, such as ordering at a restaurant or answering the telephone, can cause panic. People with social phobia often go out of their way to avoid public situations.
