If you read my book The Psychopath Code you'll see my discussion on "grounding", which is a simple (yet hard) technique for keeping yourself free of destructive emotions.
That book, BTW was absolutely panned on Reddit since I'm not a psychologist. I watched hundreds of comments telling me to fuck off, to kill myself, how did I dare discuss such things without credentials.
And at the same time I watched my book sales spike up to 10 times more than ever before, and I chortled like a gleeful madman...
Sometimes it's really just a matter of perspective and I'm usually good at finding the right perspective on things.
