Yeah man, some great advice here. I think many of us have had that feeling, that's why we jumped in. I myself felt pretty unsure of myself for the first year or so. The "not drinking" thing was fine, but it was the life outside that was giving me problems.
I remember thinking "I've never even asked a girl out on a date without being drunk"...and then it hit me. I'd never learned how to behave like a sober adult. It's a learning experience and yeah it takes time. Sober conversations and getting comfortable outside of your couch/laptop space takes time. It will happen, though. You'll get your groove and your confidence back. Just keep plugging away and do not drink. You'll pick up speed here in a bit. And once you do, your world is going to start to expand so fast you'll have to hold on tight. Sobriety's a wild ride, man. Enjoy and thanks for the post!
