A little harsh,and, if I may say, patronising!
One Dot right
The only thing i was trying to say is that palpitations will be made more severe by fear. No way was I trying to say not to be checked out. Infact I would go further and say be checked out until you are convinced that your heart is healthy. Even if you have the slightest grain in your mind that the docs may be wrong the condition will be worse as many anxiety/stress conditions are generated by fear of the symptoms themselves.
There would be nothing worse fear wise than lying in bed thinking you are about to depart this world at any second with heart failure!
But having done that forget it as turning your thoughts inwards will not help at all.
Sorry you have a real "problem" but most dont.
