Definitly tell your friends and family as soon as possible. I, too, kept it from those who care for me and wished I hadn't. Believe me they know something is wrong. My best friend sat me down and flatly said " What's wrong?" He and others had noticed my condition much earlier and thought I was on drugs or something. What a relief it was to be "out of the closet" and not worry if someone noticed my tremor or wandered why I looked like a zombie. You will not regret it! Dick
