Thanks for your question on Health Care Magic.
I can understand your situation and problem.
By your history and description, possibility of
stress and
anxiety related symptoms is more.
But better to rule out cardiac cause because you are having
hypertension.
So first get done ecg and 2d echo.
If both are normal than no need to worry for heart diseases.
You are having stress related symptoms mostly.
So better to
consult psychiatrist and get done counseling sessions. Try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs too.
So don't worry, you will be alright.
Avoid stress and tension, be relax and calm.
First rule out cardiac cause and consult psychiatrist.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
