I well understand the fatigue and desire to get a break from all the shitty stuff going on in the world, but I don't think it's anyone's responsibility but yours to curate your feed to tone down what you see.
If you are interested, may I suggest you build a few lists populated with accounts that will meet your desire for fun or silly or intellectually stimulating or the arts or whatever you like.
That way anytime you need an uplift fix, you can be confident of getting what you need.
