What is the reason for anxiety?

Anxiety may be caused by a life event, a physical condition, psychological stressors which have accumulated, or a combination of these. Certain people may be more anxious in their daily lives and thus may be more predisposed to anxiety. Anxiety is commonly tied to a number of diagnoses like ADHD, OCD, phobia, social anxiety, and depression, for example. That said, it can be treated and the effects can be mitigated.
