Thanks for your question on Chat Doctor. I can understand your concern. Since your Holder monitoring (48 hour continuous monitoring of ECG) is normal, no need to worry about arrhythmia or heart related diseases. Your symptoms are mostly due to uncontrolled anxiety. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need additional anxiolytic Chat Doctor.
