Agoraphobia is an anxiety disorder characterized by anxiety in situations where the sufferer perceives certain environments as dangerous or uncomfortable, often due to the environment s vast openness or crowdedness. These situations include, but are not limited to, wide-open spaces, as well as uncontrollable social situations such as the possibility of being met in shopping malls, airports, and on bridges. When you are in a feared place you become very anxious and distressed, and have an intense desire to get out. The anxiety usually causes physical symptoms such as: a fast heart rate, palpitations, shaking (tremor), sweating, dry mouth, feeling sick, chest pain, headaches, stomach pains, a knot in the stomach , fast breathing. You may even have a panic attack. Cognitive behavioural therapy (CBT) helps you to change certain ways that you think, feel and behave. It is a useful treatment for various mental health problems, including phobias and antidepressant therapy will help to solve the problem.
