First of all, why are you using ">" like some weeb out of 4chan?
Second of all, if you couldn't deduct specific characteristic traits out of depression, then how would it even be possible to diagnose it in the first place?
"implying childhood neglect doesn't lead to psychological problems, such as depression"
Strawman. Did I say so, otherwise?
"Doesn't mean, those are insignificant."
If you recall correctly, this it the internet we're talking about, where people for one tend not to be so familiar with the bigger picture typicailly, such as seen in #16. Just experiencing low mood for a few days following a breakup with your egirl does not qualify one for a proper diagnosis. Second of all, this once again being the internet, it is totally not as if one could just fabricate a pack of nonsense and just report it as he/she wishes. Especially not considering the fact that the rise of social media has all turned us into attention whores to a certain degree.
