The following is food for thought.
Reasons to address anxiety disorders and their symptomsGeneralized anxiety disorder--Exaggerated worry about health, safety, money, and other aspects of daily life that lasts six months or more. Often accompanied by muscle pain, fatigue, headaches, nausea, breathlessness, and insomnia.
Phobias--Irrational fear of specific things or situations, such as spiders (arachnophobia), being in crowds (agoraphobia), or being in enclosed spaces (claustrophobia).
Social anxiety disorder (social phobia)--Overwhelming self-consciousness in ordinary social encounters, heightened by a sense of being watched and judged by others and a fear of embarrassment.
Post-traumatic stress disorder (PTSD)--Reliving an intense physical or emotional threat or injury (for example, childhood abuse, combat, or an earthquake) in vivid dreams, flashbacks, or tormented memories. Other symptoms include difficulty sleeping or concentrating, angry outbursts, emotional withdrawal, and a heightened startle response.
Obsessive/compulsive disorder (OCD)--Obsessive thoughts, such as an irrational fear of contamination, accompanied by compulsive acts, such as repetitive hand washing, that are undertaken to alleviate the anxiety generated by the thoughts.
Panic disorder-Recurrent episodes of unprovoked feelings of terror or impending doom, accompanied by rapid heartbeat, sweating, dizziness, or weakness.
