Q: I don t eat nearly as much as I used to and worry about getting enough vitamins. Should I take a supplement?

Q: I am 70 years old and in good health, but I ve always been a worrier. I worry about my husband's health (he had a heart attack) and about our children and grandchildren, even though they are all doing well. Lately I'm not sleeping well, I can't concentrate on anything, and my heart feels like it's racing. Is this normal, or am I too anxious?
