This decade is incredibly formative in determining who we are. And sometimes this doesn't always align with who we thought we were three to four years ago, or even three to four months before. It's really okay to outgrow people, but what can come with that can be really intense feelings of isolation and loneliness. We are all innately, intrinsically social creatures. A balanced amount of social interaction is as fundamental to our well-being as things like a balanced diet or getting sleep.
