Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Stress is known to precipitate with anxiety symptoms such as palpitation and breathlessness. These are natural defense mechanism of the body. Prolonged stress causes some hormonal changes inside the body. These hormonal changes induces fear related symptoms and that causes anxiety. Palpitation is part of it. Even medicines cannot relax you for ever. But relaxation techniques like breathing practiced twice daily can be of immense help and can cure your problem. You can post a direct question to me in this website. Include every detail as much as you can. I shall prescribe some psychotherapy techniques to control your condition. I am sure that the techniques should be a success. Hope this answers your query. Available for further clarifications. Good luck.
