So sorry that you're hurting because of the shunning. That's what the shunning's supposed to do - hurt you so much that you want to crawl back on your hands and knees and beg the shunners to forgive you.
We should mourn that our blinded shunners are unable/unwilling to assimilate any of the information which exposes their beloved organization, and not that we've lost such cult-directed friendships. It hurts to know that sincere love and compassion can be repaid in such an inhuman way. I hope you make new and better friends soon.
