Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Possibility of
stress and
anxiety related symptoms is more.
But better to rule out heart diseases first.
So get done ecg and 2d echo to rule out cardiac diseases.
If both are normal then no need to worry for heart diseases.
Stress and anxiety appear more likely cause in your case.
So avoid stress and tension. Be relax and calm.
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.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
