I moved across the country and had to rebuild my social network from scratch without social media, you can do this through sites like meetup or checking local event calender's.
Once you meet some folks who you want to know better you can exchange numbers and quickly set up a coffee, tea, lunch, dinner thing and then get into the habit on checking up with them to see what they are doing. Once I established this relationship with people they began to invite me to things every once in a while, do this with 3-5 well connected friends and you should have options every weekend.
People are outsourcing the management of their social life through Facebook, if you want to stop using Facebook you really need to take back control of managing your social network.
Needs, that's comical. Facebook is not a need.
I'm 31 and I've never used tobacco. If people who used tobacco just made better choices they could be like me. They really need to ask themselves if tobacco really makes them happier. /s

I suppose it's a bit facile to compare Facebook to an addictive drug, but the idea that just because you've never used Facebook, nobody else should want to doesn't make any sense. Not everybody's circumstances and background are going to look like yours and people will have different needs. My friends probably have a very different dynamic than your friends so what works for you might not work for me or vice-versa.
