Books to revive the whimsy in life and/or that helped you face adulting

Everything feels super heavy right now and I'm just so scared and tired of everything. I feel super anxious all the time and I really need a cosy book that hasn't got anything to do with motherhood, romantic relationships, unemployment, financial worries, death/grief, divorce, violence, war, illnesses and diseases, that shows me there are good parts of being an adult too. Something that feels mundane, or very much slice of life. Could be nonfiction too. Something to remind me of the beauty that's still in this world, or that there are fascinating and fun things to get hyper fixated on still and it's not all bad dystopian shit. Got any recs? Thanks.
