Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, your symptoms are mostly due to uncontrolled
stress and
anxiety.
No need to worry for heart diseases as your all heart reports are normal.
You are also taking anxiolytic drugs.
But sometimes, only drugs are not important.
Along with drugs,
counselling also plays very important role in appropriate control of anxiety.
So
consult psychiatrist and get done counselling sessions.
Try to identify stressor in your life and start working on it's solution.
Don't worry, you will be alright. Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
