For me, the coping was while in the org. Leaving brought me much happiness, and a "life". My family who are involved (and there are quite a few) were never very loving anyway, they were and are robots of the wt. Actually, I am so much more of a person now with peace of heart and mind, that I find it much more enjoyable when I do talk or visit with them. The hardest thing is to see them living their robot lives and talking their robot talk... and knowing there are real people under it all - they are just so totally convinced and indoctrinated out of their desire to be right and win the prize dangled in front of them.
The organization has denied them much in life as it did in mine, till I de-programed my mind with the simple chant of "I will not feel quilty". But I must admit that the feelings of, not belonging anywhere, being a misfit, along with the guilt stuff can haunt me, if I let them, and only if I let them. There are times when those feelings will catch me off-guard, those are probably the most difficult times to deal with. Sometimes the family tries to "push buttons" even if unwittingly - that's when strength is needed on my part to take a step back and think before I automatically react.
I left along time ago and it took time to learn to listen to and accept my gut feelings (which has always been right) instead of letting the old programing in my head control me.
