ANXIETY/FEARS/PHOBIAS
Anxiety is a normal human emotion that everyone experiences at times. Many people feel anxious, or nervous, when faced with a problem at work, before taking a test, or making an important decision. Anxiety disorders, however, are different. They can cause such distress that it interferes with a person's ability to lead a normal life.
An anxiety disorder is a serious 
mental illness. For people with anxiety disorders, worry and fear are constant and overwhelming, and can be crippling.
Anxiety disorders are characterized by excessive feelings of anxiety and fear, [1] where anxiety is worry about future events and fear is a reaction to current events. [1] These feeling may cause physical symptoms such as a racing heart and shakiness. [1] There are various forms of anxiety disorders, including generalized anxiety disorder, phobic disorder, and panic disorder. While each has its own characteristics and symptoms, they all include symptoms of anxiety. [2]
Anxiety disorders are partly genetic but may also be due to drug use including alcohol and caffeine. They often occur with other mental disorders, particularly major depressive disorder, bipolar disorder, certain personality disorders, and eating disorders. The term anxiety covers four aspects of experiences that an individual may have: mental apprehension, physical tension, physical symptoms and dissociative anxiety. [3] The emotions present in anxiety disorders range from simple nervousness to bouts of terror. [4] There are other psychiatric and medical problems that may mimic the symptoms of an anxiety disorder, such as hyperthyroidism.
