Do you stop giving a shit about important things when you’re tired?

Yes... quite. I become apathetic. If tired or fed up.

I don’t give a shit about important things most of the time. Which is why i procratinate until whatever it is, is due soon, and then i freak out and finally get things done. I struggle with motivation

I guess your body does tell you to prioritize itself because any day health is a bigger emergency ans urgency than any other.. the body knows how to self preserve..

Not just when I am tired pretty much all the time I don't give a shit. Life's easier that way when you just don't care.

If only one could alter themselves like that

All the time.

Sometimes
