> 3. Nobody tweets about their hemorrhoids. Or abortion.

There's an informal support group that tweets about perinatal depression, OCD, and psychosis. This includes people who've taken the choice to have abortion (or even sterilisation) rather than go through what they went through before. ((Watch out, this is just an informal group and there's not much in the way of clinical or data governance.))

Here's a british men's health magazine advertising itself with advice about hemorrhoid prevention: https://twitter.com/MensHealthMag/status/752076400102895616

I pretty much only tweet about treatment for mental illness.

I'm not sure how useful this kind of stuff is to other people.
