well, having a realization like this at your young age means that you're in a position to feel much better than most people from this point forward. i'm almost (but not quite!) twice your age and it was only about a year ago that i had a similar epiphany about the importance of living life in the real world. i stopped reading the news, got off of all social media (except for a handful of subreddits), and started to focus on dealing with what actually enters my life. i'm much better off for it.
