Your first problem you need to solve is that you have nothing else to talk about except your job / programming. To fix this, you need to pick an activity or hobby. The less "you" the activity is the better. Your current state of activity has been not satisfying your desire for social interaction. You can say your current way of choosing activities has given rise to your current state of activity. Therefore, change the way you choose an activity. I was in the same boat a few years ago and I chose improv as my activity. Choose something that you do with other people live. Once you choose your activity. Be the guy that's always down to do stuff. Be the guy that is always willing to host a get together or hang out after the activity. I highly recommend improv just because it's so social and it's lots of fun. It also takes everyone out of their comfort zones and everyone starts off on the same foot which gives you a sense of family.
