Anxiety is an emotion characterized by an unpleasant state of internal turmoil, which is often accompanied by nervous behaviors, such as going back and forth, somatic complaints and chewing.  This is a subjectively unpleasant feeling of fear of anticipated events, such as the feeling of near death.


Anxiety is not the same as stress, which is a response to a real or perceived immediate threat, while fear is an expectation of a future threat. It is often accompanied by muscle tension,  restlessness, fatigue and problems with concentration. Anxiety may be appropriate, but when experienced regularly, you may have an anxiety disorder.

People struggling with anxiety can withdraw from situations that have caused anxiety in the past. Here are different types of anxiety. The Existential anxiety can occur when a person faces anxiety, existential crisis or nihilistic feelings. People can also face mathematical anxiety, somatic anxiety, tremor or anxiety. Social anxiety and foreign fear arise when people are afraid of strangers or other people in general.


The first step in managing a person with anxiety symptoms is to assess the possible presence of a basic medical reason, the diagnosis of which is necessary to decide on the correct treatment. Anxiety symptoms can mask an organic disease or appear in a relationship or as a result of a health disorder.


The anxiety may be a short-term “condition” or a long-term “feature”. Anxiety disorders are partly genetic, but they can also result from the use of drugs, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety), as well as withdrawal from drug abuse.



They often occur with other psychiatric disorders, particularly bipolar disorders, eating disorders, depressive disorders or some personality disorders. Typical treatment options include lifestyle changes, medication, and therapy.





Anxiety is different from stress, which is an adequate cognitive and emotional reaction to the perceived threat. Anxiety associated with specific reactions during a fight or flight, defensive or escape. Occurs in situations that are perceived as uncontrolled or unavoidable, but unrealistic.


David Barlow defines anxiety as a “future-oriented state of mood in which you are not ready to try to deal with upcoming negative events” and that is the distinction between future and current threats that divide anxiety and fear. Another description of anxiety is agony, fear, terror and even fear.


Symptoms of anxiety may include number, intensity, and frequency, depending on the person. While almost everyone has experienced anxiety at some point in their lives, most of them do not develop long-term problems with anxiety.
