Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Cardiac enzymes are very sensitive and specific in determining cardiac diseases.
Since you are having normal enzymes, no need to worry for heart diseases.
You are also having stressful life. So possibility of stress and
anxiety related symptoms is more.
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 avoid stress and tension. Be relax and calm.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
