Facebook was one of the first social networking sites that I had heard about. I only recently made an account for myself. Everyone had it for so long but I found that type of stuff boring. They had so many friends on it and how many shares and likes their content got. It was a way to connect with those around you, without you leaving your house.
School is either that awesome period of your life where you make a ton of friends who will stand by you your whole life, or it can become one of the loneliest places on the planet and can give you depression and anxiety. There is no in between. The grades and the classes you study are like the small print in the terms and conditions. The people around you and the emotions they ensue are what really affect you.
