One thing I have absolutely been through the wringer over is mental health.
I half wonder if it would somehow be interesting to collect my comments on this very site, because I have been here long enough that for most of the time – everything but the last two years, in honesty – my issues were uncontrolled. They were uncontrolled because they were unidentified; and they were unidentified because, by and large, nobody bothered to look beyond the first ideas. It’s one thing to go by “if you hear hoofbeats, assume horses, not zebras” but to keep saying ‘horse’ when you’re staring at a stripy black and white walking barcode is taking it much too far.
To be clear: I disagree heavily with Marcus (whose blog I follow assiduously) on this one topic. I believe that psychology and psychiatry very much are scientific disciplines. Empirically, there are hordes of people out there whose lives have been improved immeasurably by psychological techniques and psychoactive medication, so something must be working. But there are also hordes of people (smaller ones I hope and believe, albeit an anecdotal opinion) who aren’t helped.
