Enjoy real life!! In the months I had no Facebook, life was amazing and I was more productive, though a bit lonely mainly because I live in a foreign country adn my family is thousands of miles away.
Both of my siblings live abroad but I stay in touch through messaging. Facebook always made me feel my relationships there were shallow, and many people I regularly interacted with never followed up off-site. For me this is a good thing. Pruning false relationships frees up time to invest properly in those relationships that really matter. Facebook gets in the way of social relationships, you can't see who really matters while you're distracted talking to people you'll probably never meet again. Quality > Quantity every time.
