My heart goes out to you my friend. Truly my friend.
I cannot begin to give you advice because I do not know much about coping with shunning. Honestly my family could shun me and it would not really matter. I was never blessed with truly loving friends in the truth and I have always known it even when I was PIMI.
Although I love my parents, I don't really like who and what they are especially my father who is an elder and of the caliber of the ones you dealt with, so no lose really there either.
I mental prepped myself to be cut off and stopped caring to a great degree about my parents long ago. That sounds horrible I know, but true. We are CULT survivors so our experiences are anything but normal. For me if it happens I will leave with all my emotions and peace of mind fully intact. No one is worth the price of that to ME.
If you feel like "returning to jah" just to get back to a state to converse with others you know again, then do so and don't let others judge you for it if that is what you want and how you feel.
I hope things turn out with minimal negative effects on you. I know from others that it may be rough. Please keep my profile handy and DM if you need a listening ear. I don't think I could give any good advice for you because I am not experienced in that area of JW life but I will always be encouraging!
Hold your head up high however because it is clear as rain that the WT is falling and with, either willingly or unwillingly, release those captive in her at some point. I strongly, based off of what is internally going on and the crippling events they are sustaining for now, that it will happen in the very near future.
Take care and best wishes.
