Anxiety is a normal response to stress, which can help an individual to deal with a situation. However, anxiety is a problem if it is experienced to such an extent that it interferes with a person's life.
Symptoms can include:
Treatment is needed both for the relief of symptoms and for the underlying anxiety.
Panic attacks are a particular type of anxiety response. These may often involve severe anxiety with physical and psychological symptoms. Attacks are not predictable and may not appear to have any cause.
A phobia is a fear that is out of proportion to a situation. People with phobias will try to avoid the cause. Phobias can be fears shared by many other humans such as heights, dangerous objects etc. Some may develop as a result of a particular situation such as a car crash, mugging etc.
Social phobia, which is common in depression, is a fear of interacting with people in the normal ways, talking, sharing meals, public speaking etc.
