Prolonged extreme stress, sudden fear factors, shocks from life events, life threatening illness etc can cause these type of psychological disorders, in which anxiety and fear about surroundings or people will be promenent symptoms.
Anxiety disorders are a category of mental disorders characterized by feelings of anxiety and fear, where anxiety is a worry about future events and fear is a reaction to current events. When a person fears about something now (which may or may not happen in the future) and if he do it repeatedly, it is called anxiety disorder. These fear provoking feelings are called anxiety and it may cause variety of physical symptoms, such as a racing heart, restlessness, helplessness and shakiness. There are a number of anxiety disorders: including generalized anxiety disorder, a specific phobia, social anxiety disorder, separation anxiety disorder, agoraphobia, and panic disorder among others. While each has its own characteristics and symptoms, they all include symptoms of anxiety. I need to know more about your anxiety so that I will be able to diagnose it properly and provide you counseling and psychotherapy to overcome and manage your anxiety. Take care.
