By dedicating a certain amount of time for things I enjoy while pretending that the world outside doesn't exist. That time when I watch an anime, or read a book, or write fanfiction, or cook something delicious... that keeps me sane, it keeps me from falling back on my natural tendency to focus on all the bad things and ignore the good in the world.

You cannot allow yourself to be in that "constant stress" because it wears you down and grinds your sanity and willpower like a big belt sander.

That timeout revitalises me, and gives me the balance to deal with the stresses and worries about everything else.

Obviously there isn't a silver bullet, and mindfulness is probably the best bet here.
