Maybe start off by realizing that Facebook is pretty fake to begin with? That way you can stop feeling pressure to post things. Many people are private and don't feel the need to broadcast every moment of their lives....in that sense, not being active on social media doesn't make you an antisocial loner, rather, it just means you like privacy. I think that if you really start to use Facebook more and more, you'll see what I mean. People only post the good stuff, the happy stuff and make themselves look perfect, or use it as a way to complain about the most idiotic things in the world (which just makes them look stupid). I have stopped using Facebook a number of times, but stupidly I go back....only to MAJORLY regret it later. Then again, I'm a pretty honest person and I hate any hint of fakery, so social media really isn't my cup o tea.
