Sorry, this is not what you asked for but there is another way to deal with this issue: develop compassion.
It is very very hard to be compassionate about someone we view as an enemy or a very bad person or at least an annoying person. Even a mention of their name can aggravate us. We react viscerally and involuntarily. The surprising effect of developing compassion towards them is that it takes that power away from them.
Think of them as people – think of how bad it must be to lead a vapid celebrity life or to be extremely paranoid and having the weight of being the leader of the US and not being able to trust anyone around you and not even remembering what you said yesterday and everyone laughing at you. Think of them as ordinary people put in extraordinary situations where their best is not good enough. And who knows how we would handle it if we were in the same situation. Hopefully this line of thinking will eventually reduce if not remove the fascination with these people as you view them as just ordinary people and then reading about them may make you sad but won’t spoil your day.
When I first heard this, this was very hard for me to internalize. I needed lots of practice. Even now I haven’t and I have to pause and consciously start thinking this way. I still read about Trump and what he is doing and it makes me sad to see its effect on others but I don’t get angry and I don’t remain upset for long. This certainly doesn’t mean I condone whatever he does but at least I don’t love my mind over it!
Does this make sense?
