What are 3 things that Demeter fears?

Oh, dude, Demeter, the Greek goddess of agriculture, is totally scared of losing her daughter Persephone to the underworld, like who wouldn't be? She's also freaked out by famine because, you know, it's kind of her thing to make sure crops grow and stuff. And I guess she's not a fan of someone messing with her harvest either, like, don't mess with a goddess's crops, man.
