B. The person has difficulty controlling his delusions.
C. This anxiety and delusion is accompanied by three (or more) of the following six symptoms (at least some symptoms have been found on most days of the past six months):

1. Inability to calm down (irritability) or being nervous or constantly on edge.
2. Easy fatigue.
3. Difficulty concentrating or having a clear mind.
4. Don’t get angry easily.
5. Muscle tension.
6. Sleep disturbance (difficulty falling or staying asleep, or an unsatisfying sleep that is not restful).
D. Anxiety, delusion, or somatic symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
E. The disorder is not attributable to the physiological effects of a substance (eg, a substance of abuse, a drug) or another health condition (eg, hyperthyroidism).
F. This disorder is not better explained by another mental disorder (eg, anxiety or delusion about having panic attacks in panic disorder, negative evaluation in social anxiety disorder [social phobia], contagion or other obsessions in obsession-compulsive disorder, attachment in separation anxiety disorder) separation from people, reminders of traumatic events in post-traumatic tension disorder, weight gain in anorexia nervosa, somatic complaints in somatic symptom disorder, perceived visual defects in body image disorder, having a significant illness in illness anxiety disorder, or content of delusional beliefs in schizophrenia or delusional disorder (APA, 2013).
When examined in clinical settings, it is possible to state that anxiety disorder is a very destructive disease. Because; it harms life expectancy and psychological well-being in individuals not only due to the destruction of their social functions, but also with negative effects in their work lives (Ruscio, Hallion, Lim, Aguilar-Gaxiola, Al-Hamzawi et al., 2017). In addition, generalized anxiety disorder causes more serious damage to the lives of individuals due to its long duration, being a disease that is difficult to understand and overcome (Montgomery, 2011; van Eijck, Branje, Hale, & Meeus, 2012).
