Anxiety disorders differ from the normal feelings of nervousness or worry, and include excessive fear that is usually irrational. For an individual with an anxiety disorder, feelings of anxiety do not just go away and may get worse over time.
Most people have experienced a time when they felt overwhelmed with work, personal issues, or maybe even had a huge fight with a significant other. These situations can lead to stress or worry, and almost everyone experiences this feeling at some point in their life. Anxiety is a normal emotion. It can affect an individual emotionally as well as physically, even causing serious health issues.
