There's a book by Nick Hornsby called "A Long Way Down" about four people who meet because they all went to the same rooftop in London on New Year's Eve to commit suicide. The rest of the book is a subtle, funny, really insightful look at how we change each other sometimes in very unexpected ways. There are no grand resolutions or thunderous revelations, it happens like it does in real life. They each gradually shift infintesimal bit by bit until they're somewhere else, a place where they want to live without knowing how they got there.

It's beautfully summed up by a scene at the end of the book. They all go back to the rooftop and from there you can see the London Eye, the giant ferris wheel on the bank of the Thames. One of the characters looks at it and says, "that's funny, you can't see it moving from here, but you know it's moving." I thought it was the most perfect analogy for therapy I ever heard.
