By taking a simple Depression Quiz you can start to determine if you might be truly depressed or whether this is just a short term mood issue. Usually if it's a mood then it's triggered by an event such as the death of a loved one, loss of a job, divorce, etc. A quiz, while not meant to be a form of diagnosis, will help give you more information you need to assess your situation.
I am a National Certified Counselor and have developed a depression quiz that you can take. However, it's important to note that a depression test is not meant to displace a professional diagnosis. Rather it is a guide to tell you if you should be concerned and whether you should seek a diagnosis from a mental health professional.
If you are on this page then you must be concerned that you might be depressed. I invite you to take this test and find out once and for all. It will take you less that 3 minutes.
Depression tests are only valid and reliable if they have been developed using the "Standards for Education and Psychological Testing". Which means that it needs to be developed by a professional. So if you decide to take a depression self test, don't just take any old test. Make sure that it is from a credible, reliable source.
The Beck Depression Inventory is widely used by those of us in the Mental Health Field. It is copyrighted so you won't find it on the web - legally anyway!
One important point to mention is that, once depressive disorders are diagnosed and treatment has begun, the client usually feels much better in just a few short weeks. It can be treated and it is possible to beat this - even if it doesn't feel like that right now! Take action now and you'll feel miuch better later.
On another note, do you like to write poems? I am always looking for great depression poems to publish on my site! You can create your own page on this site and share it with others. This can be very therapeutic as well.
