Do activities, friends, or possessions that gave you pleasure before no longer provide you comfort or a sense of well-being?
Have you gained or lost a significant amount of weight in the last month? (e.g., 7% of the weight of a 150 pound person is equal to weight gain or loss of about 10 pounds)
Are you sleeping too much or too little compared with one month ago?
Do you find it difficult to fulfill basic duties, roles, or responsibilities in the domains of family, work, or social life?
Are you crying uncontrollably for periods of time throughout the day?
