Hi, my name is Morgan, and I have been diagnosed by multiple psychiatrists as clinically depressed.
The good news? I've been in intensive treatment and am feeling better than I have in years.
SO. Yesterday the overlords at Google added a diagnostic survey function to their mobile search in the United States. Google "depression" or "clinical depression" and you get this handy little button.
OK, no sarcasm. The test was released in conjunction with the National Alliance on Mental Illness. It is nine questions long (known as "Patient Health Questionnaire-9" or PHQ-9) and will tell you what level of depressed you are at the end.
The test itself is not new, nor the first of it's kind. Not long after my daughter was born, I was evaluated using the widely accepted screening test Edinburgh Postnatal Depression Scale. I've also filled out lengthy (like, TL;DR lengthy) questionnaires asking similar questions every time I've sought a second (or third or fourth) opinion from any psychiatrist.
