Feel good finding myself and my peace type of Fictional Book?

I've been going through it lately, and I would like to pick up several books to just, float away from my current situation or to have a book that shares some semblance of a depressive state that heals further on the book. I want to read that it would all get better in the end, that it could also reflect on current life.

Would appreciate if:

1. There's minimal romance, or romance is not the main part of the story.

2. Happy ending, please?
