Dr. Firestein, My daughter is a high school senior and has always been a good student. In the past, she always seemed to handle stress well. She has gotten very good grades, participated in sports and served in student governance.  She does plan to go to college and has been accepted at a university a few hundred miles away. Recently, my daughter seems down a lot. Her appetite isn’t normal, she gets up in the morning with bags under her eyes, and when I ask, she says she is “worried about everything”.  How worried should I be? And how can I give her support given what she is going through?
