Passively witnessing horrible things that are happening, which you already know are happening, because someone made you feel an obligation to keep looking long after you've gained all the education you possibly could, is irresponsible and a bad use of your time.
You, as a person on the internet watching things happen, have limited resources to materially affect these things. You can donate to some fundraisers, you can share some educational resources, you can consider involving yourself in organizations that work with this stuff more meaningfully. That's about it.
If you do obtain special skills that can help with a horrible situation, what you will get hammered in there is that when you leave work, you leave work. You take breaks, because if you don't stop dealing with whatever shit you're dealing with to reset and recharge, you will get worse at your job until your mistakes start becoming a liability.
That's for people whose actions actually do something meaningful. If they are obligated to stop and rest, then you, who are just burning yourself out by looking at things without doing anything, absolutely have to.
Use the fucking mute function. Use the fucking filters.
