Moving on is the only answer, making new friends, setting new goals, living.
Living well is the best revenge as they say.
While I will never forget the friendships I made as a witness, I don't sit in my house fuming about the fact that family members and friends have shunned me for 13 years.
I have friends, I have hobbies and goals, I live. Life goes on.
Would I like to see these people again? Maybe. I recently heard from one old friend who was also disfellowshipped for about 8 months. We chatted for 5 or 10 minutes about the old days and shared a couple of funny memories. Then we quickly ran out of things to say to each other.
I'm sure my old friends barely even remember me now and my nieces, who were still children when I was DFed are now married with kids, lives and heaps of problems of their own. I doubt they think of me much either.
It is hard to keep in real touch with very many people. My experience is that most people maintain close relationships with 5 to 10 people and everyone else is on the periphery somewhere, maybe linking up when a common interest event comes up.
