If you're not interested in going back, and your relatives aren't, why wouldn't you call them?
Oh, snap! I have the mobile number here of a good friend who was disfellowshipped a few years before me. I've always been too ashamed to call her, because I went along with the shunning myself, and didn't even contact her when I found out she'd been d'd. Okay, I can relate to that. I'm going to work up the courage to talk to her today.
