When anxiety begins to retard quality of life on a regular enough basis, a teen might be suffering from one of many anxiety disorders: Generalized Anxiety Disorder (GAD) is characterized by excessive worrying, and as a teenager there's plenty of things to worry about, but GAD can transform a pimple into an agoraphobic trigger. Obsessive Compulsive Disorder (OCD) leads to compulsive actions and patterns; by achieving certain patterns of control, someone can in effect bring what is out of their control into a momentary state of submission "such as using the same number two pencil with the horizontal bite marks for English tests held on Tuesdays, only. Then, Social Phobia is another form of an anxiety disorder where one begins to fear speaking in public, eating in public, or simply being in contact with a stranger, and in the nightmare of high school diplomacy and social order, anxiety ripens with ease. Post Traumatic Stress Disorder (PTSD) occurs after an exceptionally traumatizing episode in a child's life. Sufferers find extreme anxiety in situations with any relevance to the original trauma, and often anything can trigger a flash into panic. Panic Disorder is the repeated occurrence of panic attacks induced by high anxiety and can include problems breathing, nausea, sweating, etc. Finally, another anxiety disorder is Separation Anxiety Disorder (SAD), but is more isolated from the mean teenage population who rue the presence of a parental figure "for others, though, the realization of their own potential life giving loins in adolescence can influence feelings of want for a lost parent, or of one down the hall. Being that there are so many recognized variations of one disorder, the circumstantial evidence concludes that anxiety is something as varied as it is widespread.
Now, more and more teenagers are being prescribed anti-depressant medications, usually SSRIs (Seratonin Reuptake Inhibitors).
