When having a panic attack, feelings of intense anxiety come on suddenly and people often feel that they cannot breathe, and/or think that they might die. These feelings and thoughts can then make the panic attack worse. There is often a trigger, such as going to the dentist or getting on a plane, but sometimes there is no obvious trigger. Psychological therapy can help people understand what is happening to them and provide them with ways to regain control, with the aim of reducing the severity and frequency of panic attacks. Many people can overcome panic attacks completely.
