I understand how you feel. We have 'lost' all of our friends and family. Unfortunately if you try to go back in, they still won't 'trust' you and will still have limited contact.
I know it is difficult. But we cannot get thru that cognitive resonance and mind control fromt he cult.
Please hang in there
My little brother went apostate and because the family shunned him, he killed himself. I regret that very much because, now that I am out, I wish he was still around so that we could be 'out' of the Borg together.
Point is...Don't give up. You don't know that 1, 5, 10 years from now, one of your family members may wake up and see it for what it is A Satanic cult that destroys families
