I worked on this problem for about a month straight a couple years ago (but didn't have any significant success). It's extremely draining on you; don't forget to take breaks. <3

What was your problem? (OP has deleted their comment.)

Sorry for deleting. I was working on detecting suicidal posts in social media. It is really depressing work.

Oof, yeah.

And even if you do manage to see them, sorting out how to intervene effectively --- where and when and in a manner that actually helps --- is still a Hard Problem.

I've lost a few friends this way. One I managed to intercede with. The first time....

Thank you for trying.
