Depression does not come with a big sign telling you what is wrong. Instead, it creeps up on you.
The most common indicators of depression are:
feeling tired, even after resting
feeling physically unwell
feeling tearful more easily
trouble concentrating watching TV or reading
avoiding contact with friends
The other sections give you a lot of information, and a questionnaire you can complete.
