I warned my daughter that she would be disfellowshipped and lose her friends.
She replied, "If they shun me, they weren't really ever my friends".
Her wisdom was profound. She has a huge number of friends, including ex-Witnesses. Facebook helps too.
Why should you be sad because you lost all your "friends" - who were disloyal and entirely willing to abandon you, anyway.
Actually, you might be glad that you finally see the matter with clarity now and can find friends who won't dump you simply because a group of twisted, uncaring old men ordered them to do so.
