You may think this is an easy question to answer, but it's not wise to make your own diagnosis of depression — leave that to a professional. However, you may want to ask yourself a few basic questions first:
If you can answer yes to any of these questions, especially if your answer has been yes for more than a few weeks or months, you may have a depression that needs help. It may make you anxious to seek assistance, but you may also have a lot to gain.
For some people, to be depressed means to be weak, flawed or morally tainted. The danger of this point of view is that you can become self-critical or embarrassed. You may avoid help or feel you don't deserve it. Instead of seeing depression as a problem (medical or otherwise) with a solution, it becomes a source of shame. So you may dismiss your ups and downs as a normal part of life not worthy of any special attention.
Depression is not just feeling a little down. It is diagnosed by a set of symptoms. Some symptoms indicate mild depression while other symptoms, such as considering suicide, suggest a more severe depression that requires immediate action.
Take the most honest measure you can of your feelings and experiences, and tell a health-care provider about them. Together you can discuss what would be helpful. Labeling your problems is not always so important. More important is describing your feelings and experiences in detail so helpful plans can be made, so you can feel better, enjoy life more, and be more productive in the ways that matter to you.
