I don't know how I'm going to make it through without blowing up at an elder
Why would you want to make it through without blowing up at an elder? If he does something to deserve it, let him have it. She was your grandma. You have a right to be at her funeral.
or the first person who says they're going to meet again in the new system while staring at me.
Repeat after me, "It's nice that you believe that." And walk away. If they give you any shit whatsoever, repeat our mantra...She was your grandma. You have a right to be at her funeral.
You could stick close to your non-JW uncles...not only may you be less likely to get any shit (not infront of the 'worldlies)...but if you do get any shit, your uncles will be there to see it and stand up for you.
(Edited to add [geez how stupid am I?]: I am so sorry about the loss of your grandma. I adored mind so much, she's been gone almost 10 years and I still miss her)
