Anxiety and Anxiety Disorders

Anxiety is an emotion characterized by feelings of panic, nervousness, tension, worried thoughts, and physical changes like sweating and an increase in blood pressure. It might cause you to feel tense and restless and have a faster heartbeat. It can be a common stress reaction. Anxiety is an emotional reaction to immediate danger and is more related to a fight or flight reaction. It refers to the anticipation of concern about the future and is more linked with avoidance behavior and muscle tension.


Episodic anxiety is a part of life. Anxiety disorders often involve repeated periods of unexpected feelings of intense fear, anxiety, or panic that reach the highest level within minutes. People with anxiety disorders habitually have intense, persistent, and excessive fears about routine situations. Anxiety can be helpful in some situations. It can alert you to hazards and help you to get ready for the situation and pay attention.

The feelings of panic and anxiety affect daily life and are challenging to control. You may ignore specific situations or places to escape from these feelings. Signs of anxiety might begin to appear during childhood or teenage and persist during adulthood.

What are the types of anxiety?

There are several types of anxiety disorders based on the circumstances. Some of the major types of anxiety disorders include: 

Generalized Anxiety Disorder

Generalized Anxiety Disorder is characterized by a continuous and extreme level of worry that affects your daily activities. This constant worry and stress may be associated with physical symptoms, like fatigue, restlessness, concentration difficulty, muscle stiffness, or sleeping problems. Usually, the worries emphasize everyday things such as work, family matters, chores, etc. 

Panic Disorder

This involves recurrent periods of impulsive feelings of extreme anxiety and fear that reach a peak within minutes. During an attack, several of the anxiety disorder symptoms that occur in combination include palpitations (i.e. irregular heart rhythms), trembling of limbs, faintness, sweating, and shortness of breath, etc. Panic Disorder involves a combination of both physical and mental distress.

Selective mutism

This is a failure to speak in specific situations, such as work or school, even when you can speak in other situations where you feel yourself to be at ease, such as at home and with close family members. This can interfere with social functioning and is usually observed to occur from early childhood.

Separation Anxiety Disorder

Separation anxiety disorder is characterized by the state of being in an excessively fearful or anxious situation about separation from those with whom you are attached. Symptoms of anxiety, depression, and separation anxiety often develop in childhood but can persist through adulthood. Anxiety Disorder symptoms include nightmares of being abandoned or being left behind by the crowd.


A phobia is an excessive and undying fear of a specific situation, activity, or object that is usually not dangerous. You might be aware of the fact that your fear is irrational, but you are not able to control it. Examples include hydrophobia (fear of water), metathesiophobia (fear of change) and homophobia (fear of blood), etc.


This type of anxiety disorder is when you fear and often avoid places or situations that might cause you to panic and make you feel stuck, abandoned, or ashamed. Examples include the fear of using public transportation, being in enclosed places, and fear of leaving your home. 

Social Anxiety Disorder

It is commonly known as a social type of phobia and involves high levels of fear, anxiety, and escaping from social gatherings due to feelings of humiliation, self-consciousness, and concern about being judged or perceived negatively by others.
