"We have nothing to fear, but fear itself..." Franklin D. Roosevelt
Fear is a very powerful emotion-it certainly helps to have tools to be able to keep the biggie fear(hypoglycemia) at bay. As well as all the other fears diabetes conjures up. We are fortunate to have an emergency medical system in this country, as much as it is a paralyzing, numbing experience it has saved the lives of countless PWD's and is really better then the alternative.
(having said that, Roosevelt obviously didn't have diabetes although polio must suck pretty bad too)
