I am again too sleep deprived for a proper review, just read it OK? Read it story by story by story when you need a cathartic cry. Read Boule de Suif for your "people are terrible" cry, and Two Little Soldiers for your "missed chance at love" cry and then follow it with Claire de Lune for your "the world is so beautiful" cry.

But also look up plots/trigger warnings if those are helpful to you.
