Sam's friends are starting to worry about him. Normally energetic and fun-loving, Sam has become withdrawn and sullen. He has lost weight, is constantly tired, and hasn't been showing up to lacrosse practice or to his fraternity meetings. In his conversations with others, he expresses feelings of doubt and unworthiness, and seems to be entertaining suicidal thoughts.
