Finding your tribe, not having friends at school, the different meanings of friends to different people, growing and changing groups - just keep experiencing and don't search for somewhere to belong outside yourself! 

Quote:

"Life can only be understood backwards, but it must be lived forwards." -  Søren Kierkegaard 

Inspiration: If I mention the word belonging this book should be included! It's an audiobook too
