Take step by step.
We left fading without burning exsisting relations with some witness. These days you will be surprised how they remain contact, even social gatherings. Just play the bluf game.
There is no direct answer about how to get a new social network. Don't expect a new jw style netwerk where dozens of people welcome you with a fake smile. You have to work for it., except you choose for s new sect style life.
Real friends are rare. Choose them wise.
