Anxiety and BP. For further.

In the first week of June due to corona fobia and stress and anxiety my BP was elevated . I consulted to cardiologist who prescribed ECG and Troponin T test. There is no problem detected in test and I was advised medication I.e. starpress xl two times in a day and telma 40 in morning and alprex in night for 10 days. Further my bp was normal . After 10 days dr asked to do tmt test. The said test is also fine and there is no problem and then dr asked me to continue the medication for 6 months. If I am normal then why there is a need for continuation of BP medicine. BP high only one time is a sign of hypertension and the person has to take medicine for whole life.. kindly suggest pls what to do further . My the last one week my BP is in and around 120/80. Pls advice asap what to do pls . Need expert advice for the cardiologist for further.
