How is depression diagnosed?

A formal diagnosis will have to be done by a practitioner. However, you can read through the 9 symptoms that doctors rate the presence of to determine a diagnosis of major depressive disorder (a person need have 5 of the 9 symptoms present for at least 2 weeks).

The good news is, you don't need to have a formal diagnosis to begin treating your depression...in fact you don't even need to have 5 of the 9! As you determine which symptoms you have, you can begin to treat each of them in your own way. For example, if you are having trouble sleeping, you can start an exercise regime to help tire out your body and get you ready for sleep. You can change your eating habits to not include spicy or sugary foods before bed. You can drink some chamomile tea to help calm your nerves. You can do some meditation to quiet your mind... you see, the possibilities are endless!

So really take a look at what the symptoms are of your personal depression, and try to make small changes where you can. Remember that there is no "magic bullet" to treating depression, so with or without a diagnosis, (and with or without a prescription antidepressant), you'll probably find that seeking a variety of treatments is what will help you cure your symptoms.
