>I don't know. Depression has been recorded for thousands of years, so either society has always been insane (quite likely), in which case it's not likely to turn around any time soon, or there are other causes of depression. Some people can also fall into a depression for no identifiable reason (I can vouch for that from experience).
Of course there have always been depressed people, but the modern phenomenon where supposedly 10% of the population will have it in their lives, or where entire countries experience skyrocketing suicide rates, is certainly not related - I find it very difficult to believe that they all have a biological problem, instead of a cultural or societal problem.
>SSRIs and SNRIs and other medications have saved my life and some of my sanity, and I have high confidence that it's not a placebo - for me - having tried and failed with probably a dozen of these over the years, before hitting on a workable combination.
I don't doubt this - I only said that the vast majority of sufferers of depression do not seem to suffer from a biological problem. From my personal experience, I have seen that most of the depressed people I have known have gotten better not through medicine or medical procedure, but by consciously trying to make their lives better and be the best person they can be. Obviously this won't work for everyone - there really is such a thing as biologically-caused mental illness (see: schizophrenia, for example), but I think it is much rarer than people are willing to admit.
>But that's just me, so this is anecdata.
All data is anecdata. It's not worthless just because it happens to be your actual life and not collated and tallied by some detached scientist, it has meaning and value even without being a part of some anonymous dataset you can take confidence intervals on.
