Anxiety disorders usually do not cause death problems or sudden death, so there is no need to be too nervous. Because anxiety disorders may sometimes show some physical discomfort, such as headache, dizziness, nausea, vomiting, panic, tachycardia, palpitations, and sometimes precordial discomfort, or even some pain in the precordial area, like myocardial infarction, angina pectoris, and other manifestations. In severe cases, there is also a feeling of breathlessness, crushing and suffocating, which may be accompanied by strong fear and anxiety, thinking that they are dying, that is, a sense of near death. But the near-death feeling can usually be recovered by itself without special treatment, especially if you shift your attention and use some relaxation methods in time, so the acute attack of anxiety disorder can be recovered in a few minutes to ten minutes. The main reason why anxiety disorder patients are worried about sudden death is because they have anxiety disorder, which makes people too anxious, such as always worrying about dying, and some anxiety disorder patients have a sense of near death, which can easily make them too nervous and anxious, fearing that they will die suddenly. But anxiety disorders are generally not sudden death, because anxiety disorders are a neurological disorder and a mild psychological disorder, so do not be too nervous.
