i think that thereās a level to which this is possible physically (calling out sick or skipping class if youāre a student or whatever) but even if thatās not possible emotionally checking out + going through the motions and making space and time for your recovery afterwards is almost always how you beat a bad day
for me if the vibes are atrocious beyond reason iāll call out of work, clean my apartment, then go for a walk, go to the jewish deli and get an egg + pastrami hash on a kaiser roll and a coffee, then go home and either watch tv, play video games, and if iām feeling up to it later do some kind of writing or reading or other enrichment activity (and sometimes enrichment just isnāt on the table at thatās cool too)
whatever your comfort rituals / little treats are, pull out all the stops and really just stop for a second, take a breath, and let yourself just be, and itās guaranteed to make getting through it easier by making the day less hard, or giving yourself something to look forward to afterwards
