The three types of phobias are specific, agoraphobia, and social phobia. Specific phobias are fears of a specific thing or object, for example, a fear of spiders, a fear of needles, or a fear of cars. This is the most common group of phobias. Agoraphobia is a fear of being in a situation where someone may have trouble escaping, may become embarrassed, or may have a panic attack. This includes a fear of being alone in an unfamiliar place, a fear of being in a large crowd, or the fear of being in a particular space. Agoraphobia may result in a person not being able to leave their home because of crippling anxiety. Social phobia is a fear of being in social situations where they may be humiliated in front of others. Social phobia sometimes results in people fearing social interaction so intensely they may not be able to hold a job, go to school, or have healthy relationships.
