> Yes that is one very narrow and specific cause of the symptoms of depression. but it is by no means the only thing that causes depression in humans. I think it's a problem of terminology really. Grief and depression look very similar to an outside observer and are often conflated, but there are several other mental states that all look pretty similar and are labeled under the umbrella of 'depression' too. Many of them are relatively temporary. I think the kind of depression parent is talking about is the one that's behind the significant and rising percentage of people being diagnosed with, and treated for, depression. Over 10% of the population in the US is on an SSRI, and that cannot be a good sign for society.
