Anxiety: Is it in your family?

Came across an interesting tidbit on about some studies of anxiety running in families (LINKED HERE).  Although many relatives are loathe to admit histories of mental illness in families, I do believe this to be true.  There are several people in my extended family who have had their personal struggles with depression and anxiety, as well as some within the family tree.  However, many people are embarrassed to admit seeing signs in their elders or in passing this type of information down.  Personally, I think it could help the next generation to notice any signs that occur and get help sooner.  What are your thoughts?
