(also, FWIW, I've taken a ton of those online psych tests and nearly all of them say that I do suffer from major depressions. I just can't afford therapy to get a real diagnosis. However, I know what has triggered them - usually a major disappointment, often a breakup. I never get as bad as the "cannot get out of bed, never showers" people, but I do indeed find myself perpetually distracted and unable to be as productive as I would like, and that I am deeply, deeply boring, especially to people who do not want to hear me picking through the tangle of my failed relationship with Bingo The Great, etc. So once again, there's another anecdote for you!)
