Why people find it emotionally difficult to keep secrets?
The dynamic shows up very early in childhood (search for "google: louise ck secret"), it can involve self-sacrifice (confessing to a crime), and people find it relieving to share secrets even in completely anonymous and impersonal ways ("google: the confession bear meme").
I think it's an evolved mechanism that favors group cooperation. If people feel emotionally motivated to be open and honest with each other, and maintain a history of doing so, they're more trustworthy to each other and can coexist more peacefully and productively
