Types of anxiety
Existential anxiety

Theologian Paul Tillich characterized existential anxiety[5] as "the state in which a being is aware of its possible nonbeing" and he listed three categories for the nonbeing and resulting anxiety: ontic (fate and death), moral (guilt and condemnation), and spiritual (emptiness and meaninglessness). According to Tillich, the last of these three types of existential anxiety is predominant in modern times while the others were predominant in earlier periods. Tillich argues that this anxiety can be accepted as part of the human condition or it can be resisted but with negative consequences. In its pathological form, spiritual anxiety may tend to "drive the person toward the creation of certitude in systems of meaning which are supported by tradition and authority" even though such "undoubted certitude is not built on the rock of reality".
According to Viktor Frankl, author of Man's Search for Meaning, when faced with extreme mortal dangers the very basic of all human wishes is to find a meaning of life to combat this "trauma of nonbeing" as death is near and succumbing to it (even by suicide) seems attractive.
The "father" of existentialism, Søren Kierkegaard, regarded all humans to be born into despair by default (in The Sickness Unto Death). Such despair was created by having a false conception of the self. He regarded the mortal self which can exist relatively, and therefore be born or die, as the false self. The true self was the relationship of self to God, rather than to any relative object.
Test anxiety
Test anxiety is the uneasiness, apprehension, or nervousness felt by students who have a fear of failing an exam. Students suffering from test anxiety may experience any of the following: the association of grades with personal worth, fear of embarrassment by a teacher, fear of alienation from parents or friends, time pressures, or feeling a loss of control. Emotional, cognitive, behavioral, and physical components can all be present in test anxiety. Sweating, dizziness, headaches, racing heartbeats, nausea, fidgeting, and drumming on a desk are all common. An optimal level of arousal is necessary to best complete a task such as an exam; however, when the anxiety or level of arousal exceeds that optimum, it results in a decline in performance. Because test anxiety hinges on fear of negative evaluation, debate exists as to whether test anxiety is itself a unique anxiety disorder or whether it is a specific type of social phobia. In 2006, approximately 49% of high school students were reportedly experiencing this condition.
While the term "test anxiety" refers specifically to students, many adults share the same experience with regard to their career or profession. The fear of failing a task and being negatively evaluated for it can have a similarly negative effect on the adult.
Stranger and social anxiety
Anxiety when meeting or interacting with unknown people is a common stage of development in young people.
So-called "stranger anxiety" in younger people is not a phobia in the classic sense; rather it is a developmentally appropriate fear by young children of those who do not share a loved-one, caretaker or parenting role. In adults, an excessive fear of other people is not a developmentally common stage; it is called social anxiety.
A more common social anxiety in adults, though, is the stress and anxiousness that occurs when one (of any age-group) fears he will be separated from a group or other emotionally close person/object. This is known as separation anxiety, and occurs more frequently in adults (7%) than in children (5%).
TREATMENT OPTIONS

Cognitive-Behavioral Therapy (CBT)
Many therapists use a combination of cognitive and behavior therapies, often referred to as CBT. In this type of therapy the patient is actively involved in his or her own recovery, has a sense of control, and learns skills that are useful throughout life. CBT focuses on identifying, understanding, and modifying thinking and behavior patterns. When a person changes thinking and behavior, emotional changes usually follow. Because CBT teaches skills for handling anxiety, patients who learn and practice the skills can use them when needed.
Cognitive Therapy The goal of cognitive therapy is to change unwanted and disturbing thought patterns. The individual examines his or her feelings and learns to separate realistic from unrealistic thoughts.
Behavior Therapy The goal of behavior therapy is to modify and gain control over unwanted behavior. The individual learns to cope with difficult situations, often through controlled exposure to them.
Relaxation
Techniques for relaxing help people develop the ability to cope more effectively with the stresses and physical symptoms that contribute to anxiety. Common techniques are breathing retraining and exercise.
Medication
Medicines can be very useful in the treatment of anxiety disorders, and it is often used in conjunction with one or more therapies above. Sometimes antidepressants or anxiolytics (antianxiety medications) are prescribed to alleviate severe symptoms so that other forms of therapy can be effective. Depending on the person, medication may be either a short-term or long-term treatment option.
