List and describe the four major catagories of anxiety disorder?

I need an orginal example for each one but the only problem is, is that I have only found two. Does anyone know the four and know of examples that I could use to go off of when I use my own examples once I understand this better?

The four major anxiety disorders are GAD, Panic Disorder, Phobias, and OCD.

OCD= obsessive complosive disorder
GAD = General Anxiety disorder

The people with Generalized Anxiety Disorder cannot seem to express what they are afraid of. It is clear that they are afraid of something and have an extremely difficult time handling everyday worries.

Those with Panic Disorder have intense feelings of terror which strike suddenly and with no warning. These attacks are usually brief and can cause shaking, dizziness, and difficulty with breathing.

Phobias are usually involving specific fears, which sets them apart from GAD and panic Disorder. There is a certain something which a person is afraid of that in reality poses little or no danger to them.

Obsessive-Compulsive Disorder (OCD) is a disorder involving anxious thoughts and/or rituals which a person cannot control. A person with OCD may be plagued by intrusive thoughts or images in their mind. They could also have irresistible urges to act out specific rituals.

O.C.D comes in various forms (obsessional about hygiene/fear of contamination, performing ritual tasks, constant checking etc

Social anxiety disorder- persistant and high levels of anxiety in social situations leading to avoidance and safety behaviours

eating disorders (bulemia, anorexia) irrationally anxious and obsessive about one's appearance

Phobias- agaraphobia; fear of large open spaces, arachnaphobia, fear of flying
