Phobia

A phobia is excessive fear of one particular object or situation. For example an excessive fear of:

Animals or insects (dogs, spiders, etc.)

Natural environment (storms, water, etc.)

Specific situations (tunnels, heights, etc.)

Other types (vomiting, clowns, etc.)

People suffering with phobias will avoid the feared object/situation at any cost. Anxiety is triggered in the presence of feared stimuli or when anticipating the feared stimuli.
