Anxiety is a feeling of tension associated with a sense of threat of danger when the source of the danger is not known. In comparison, fear is a feeling of tension that is associated with a known source of danger. I believe it is normal for us to have some mild anxiety present in our daily lives. Everyday that I can think of I have some kind of anxiety though out that day. Anxiety warns us and enables us to get ready for the ‘fight or flight’ response. However, heightened anxiety is emotionally painful. It disrupts a person's daily functioning.
Anxiety can be seen with several other emotional disorders including the following:
Acute Stress Disorder
Panic Attack
Agoraphobia
Phobia
Anxiety Disorder Due to Medical Condition
Post-traumatic Stress Disorder
Generalized Anxiety Disorder
Substance-Induced Anxiety Disorder
Obsessive-Compulsive Disorder
