It may look complicated to you, but they are simply signs of hypoglycemia.
Symptoms of anxiety attacks can affect any organ or part of the body. It is due to overproduction of adrenaline the fear/stress hormone, brought about by an internal biochemical abnormality. It is biological in nature and is unlikely to respond to talk therapy. Drugs can mask some of the symptoms but NOT cure anxiety attacks.
