Anxiety can result from several things; pressure, stressful conditions/circumstances, physical pain, etc. Treatment for anxiety can include pain medication, a change in diet, exercise, pill medications such as Zolaft, Paxil, etc. Anxiety can also result from schizophrenia or other phsycotic illnesses. Treatment for these include psychiatry, therapy, anti-psychotic, anti-tremor, etc. Hope this helps! :)
