New horrors are born every day. Many people seem to think there's some kind of obligation to be informed about all of them, to have an opinion on all of them, to have some kind or prepared statement about them to weave them back into the grand narrative of whatever ideological clique you're a member of. More than all of that, many seem to think that there's some sort of obligation to look at these horrors – to stare at them until your eyes bleed, drinking them into your soul, forcing yourself to feel the proper pain, fear, grief, or humiliation. As if that's some kind of penance for not experiencing them yourself, or as if it might help those suffering, or – if it's a horror that may effect you in the future – as if it will do anything to avert it.
They're wrong. This won't help anyone. This won't make you a better person. This won't even make you more philosophically correct.
Instead, focus on what can be practically done, and who is effected, in widening circles.
If you're the one affected by the horror, do what you can to alleviate it; if you might in the future be effected by it, do what you can to prepare for it; and once you've done those things, forget about it for the moment. You'll deal with the rest when it confronts you in the street – only then will dealing with it more become necessary. In the meantime, focus on what you can do to make your life better, and on making sure you continue doing the things that give your life meaning, whether that's taking jogs, or petting your pets, or walking with your partner, or writing, or drawing, or programming.
If the horror affects your friends and/or family, or will in the future, then try to find ways to help or comfort or prepare them. And once you've exhausted the options – again, forget. You and they will deal with the future when it arrives. In the meantime, spend time with them. Enjoy life. Try to relax. Focus on doing the things that are most important to you.
If the horror affects your local community, or a subseection thereof, then do the same things as above, on a community level. This is called mutual aid.
And if the horror affects none of these things, then forget about it entirely, and refocus on other, more important things, local to you, your loved ones, or your community. You are not going to have a meaningful impact on national or global policy or politics unless you've already made it your life's mission to do. Be ready and willing to help those who have, if you see an opportunity to do so, but don't let it drain you.
Worrying about things far outside your realm of experience and control is a recipe for exhausting yourself before you've been able to do all you can for the things you can really, truly, meaningfully effect.
