Morwen, thank you for sharing your experiences. I'm so so sorry you have to go through this pain and nonsense. I'm so sorry about your baby you have lost, and I'm so happy for you that you have been blessed with beautiful children and a loving husband.
My older sister is like your younger sister. I wish my big sister thought like you. Instead she told me about three weeks ago that she tries not to think about me and tries to pretend I don't exist because it hurts her too much to think of me.
All the stuff your sister said about how much you are hurting the family and what you do affects everybody: is there a seminar that JW's go to that I somehow missed where they teach you the standarized things you should say to family members who leave!!!??? Jeez, I can't get over how much everyone sounds the same, your family and my family and so many others on this board's families all say the exact same things, like robots!
Anyway, I wish you the very best and am so glad you are doing well in spite of this. Your story really helps me to put my own life into perspective as well and appreciate the things I do have (instead of finding things to complain about all the time).
