ME,You had a Holter Monitor test with normal results and reassurance by your Dr. According to the recordings - the slight abnormalities noted never correlated with your symptom diary. Therefore, the symptoms you feel are not related to a heart rhythm problem.
This morning you shared with us that you cannot stop Googling and some friendly advise was given. From the time I was just a kid and my Mother or teacher would tell me to do something and I would respond with, "I can't", my Mother always said "Can't never done anything".
