Depression Quiz: Feeling Depressed?

While diagnosing depression isn't always easy, you can get some insight into whether your bleak mood is simply due to hormonal or situational issues or to a more clinical state of depression. Think about the last month and ask yourself the questions below. If you answer yes to more than two of them for more than 2 weeks out of 4, it may be a sign that you should talk to your doc about your symptoms; they could be associated with depression.

• Are you unsatisfied with your life?
• Do you often get bored?
• Do you often feel helpless?
• Do you prefer to stay at home rather than try new things?
• Do you feel worthless?
