Anxiety Self treatment

In some cases, anxiety may be treated at home, without a doctor's supervision. However, this may be limited to situations in which the duration of the anxiety is short and the cause is identified and can be eliminated or avoided. There are several exercises and actions that are recommended to cope with this type of anxiety:

Learn to manage stress in your life. Keep an eye on pressures and deadlines, and commit to taking time away from study or work.
Learn a variety of relaxation techniques. Information about physical relaxation methods and meditation techniques can be found in book stores and health food shops.
Practice deep abdominal breathing. This consists of breathing in deeply and slowly through your nose, taking the air right down to your abdomen, and then breathing out slowly and gently through your mouth. Breathing deeply for too long may lead to dizziness from the extra oxygen.
Learn to replace "negative self talk" with "coping self talk." Make a list of the negative thoughts you have, and write a list of positive, believable thoughts to replace them. Replace negative thoughts with positive ones.
Picture yourself successfully facing and conquering a specific fear.
Talk with a person who is supportive.
Meditate.
Exercise.
Take a long, warm bath.
Rest in a dark room.
