Oh how hurtful, so brutal. And they don't even know it! - that's the thing! O.O
Yet, in her cold-seeming, cult-clouded mind, she did voice the hope that you "take care of yourself."
I believe this part is where you can find comfort from your mom.... Her sentence, expressed, is the verbal part of her soul voicing herself to you, despite her cult indoctrination..... "Take care of yourself..." (Is it possible to allow one part of your mind to hear it from her heart, expressed in this way: "oh no! Please, take care of yourself.... Oh I hope you do take care of yourself....") and then the dub-brain would stop her from saying anymore.
You see, I too, was one of those cold, brutally harsh, horrid horrid monster-ized, deluded and TOTALY indoctrinated Dubbies!! And I believed the lies and bullshits with my whole heart, soul, mind, and goddamn strength. (Sorry, this religion really brings out all my urges to swear now, which I had suppressed for so many decades! )
You see, I am an older lady now, in my fifties, perhaps the same age as your mom... and I got hood-winked into this religion when I was around 20.... A very vulnerable time in my life... And I grabbed it and I totally believed "the truth" ... And Thought I was actually being loving and loyal and faithful and all that crap when I too complied with their harsh and horrible shunning.
I was so so so so so blinded and believing. I believed them totally, and that is so scary a thought to me, that I blindly turned my whole thoughts and life over to them. It really gives me the heebie jeebies now because THEY DON'T KNOW JUST HOW F**KING DELUDED, BRAINWASHED, AND HURTFUL -- HORRIBLY HURTFUL -- THEY ARE. They cannot see it. (-- and perhaps *this* is what will make it possible for you to eventually and hopefully forgive her if and when she can ever see through the lies....)
Though I don't believe the bible any more, the scripture, "Father, forgive them, they know naught what they do." applies when you're dealing with a totally indoctrinated JW-drone....
It hurts, yes, it hurts so much, and I am so sorry you are dealing with these terrible things all at once -- but do trust that there are moments still of grace and beauty and good things in our life too... That within the storms and shadows and fright, there are calm things and beautiful things, and still funny and cute things, and life and food and friends, and hopefully some family..... And I do hope you have pools of friendship available for you.... And know that you need not walk alone on this journey... With or, most likely, without your mom, you will get through this.
