The commonest cause of your symptoms is stress
. But it is always best to rule out the organic causes like cardiac or a lung disorder before attributing the symptoms to anxiety. You can get your pulmonary function tests and ECG done under the guidance of your physician. Getting few blood tests like hemoglobin
hormone profile will also be helpful.
I hope this information has been both informative and helpful for you.
