tribe

Can anyone share advice or their experiences? I am seeking my tribe here, but it is hard. I am an expat here, no family here, because I married a different country person I don't fit into my usual national circles, I don't have a church I can rely on and I am now single, and basically my work has me too busy to have any social life at all. But I am getting a bit lonely from just nice colleagues and casual friends, and need to find a group to connect with. But I no longer know how to go about it :( Any advice?
