There are six major types of anxiety disorders, each with their own distinct symptom profile: generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, phobia, post-traumatic stress disorder, and social anxiety disorder.

1.  Generalized anxiety disorder:
If constant worries and fears distract you from your day-to-day activities or you’re troubled by a persistent feeling that something bad is going to happen, you may be suffering from generalized anxiety disorder (GAD). People with GAD are chronic worrywarts who feel anxious nearly all of the time, though they may not even know why. Anxiety related to GAD often shows up as physical symptoms like insomnia, stomach upset, restlessness, and fatigue.

2.  Obsessive-compulsive disorder:
Obsessive-compulsive disorder (OCD) is characterized by unwanted thoughts or behaviors that seem impossible to stop or control. If you have OCD, you may be troubled by obsessions, such as a recurring worry that you forgot to turn off the oven or that you might hurt someone. You may also suffer from uncontrollable compulsions, such as washing your hands over and over. 

3.  Panic disorder:
Panic disorder is characterized by repeated, unexpected panic attacks, as well as fear of experiencing another episode. Panic disorder may also be accompanied by agoraphobia, which is a fear of being in places where escape or help would be difficult in the event of a panic attack. If you have agoraphobia, you are likely to avoid public places such as shopping malls or confined spaces such as an airplane.

4.  Phobia:
A phobia is an unrealistic or exaggerated fear of a specific object, activity, or situation that in reality presents little to no danger. Common phobias include fear of animals such as snakes and spiders, fear of flying, and fear of heights. In the case of a severe phobia, you might go to extreme lengths to avoid the thing you fear. Unfortunately, avoidance only strengthens the phobia.

5.  Post-traumatic stress disorder:
Post-traumatic stress disorder (PTSD) is an anxiety disorder that can occur in the aftermath of a traumatic or life-threatening event. Symptoms of PTSD include flashbacks or nightmares about what happened, hyper vigilance, startling easily, withdrawing from others, and avoiding situations that remind you of the event. Social anxiety disorder

If you have a debilitating fear of being seen negatively by others and humiliated in public, you may have social anxiety disorder, also known as social phobia. Social anxiety disorder can be thought of as extreme shyness. In severe cases, social situations are avoided altogether. Performance anxiety (better known as stage fright) is the most common type of social phobia.
