I tend to go with the “distract myself” method. Think about some song, movie, game, etc. Keeps the brain from ruminating on that shit. And usually can manage it long enough that the thought’s barely a vague memory afterwards.
Basically, the idea is: Don’t feed the demon.
Its data? Seems to me that most of that “data” was actually generated by users. Which Reddit, in turn, profited off for free.
