I'm attending Nar-anon and it is a blessing to have such great support there and here, too. I've detached so much from my sister and am just being the best auntie for my niece! I'm not letting my sister ruin my spirit.
As for my mom, she'll have to find her support from other sources. I think she wants the peace through me and relaying the messages, meeting discussions, etc. and I've stressed that she has to find it within herself. I can't walk her path or do her work for her. She knows this, but is so afraid of losing my sister that she's actually losing herself, too if that makes sense. As for me, I'm not going down with the ship.
Thanks for the book recommendation. I'll look into it for myself, too.
