Wow, Lib, she's still trying to stir the pot and make people explode.
That is very sick!
I think the way you win is absolutely no contact. You deprive her of the "oxygen" that fuels her own inner rage, that she expresses vicariously...by trying to spark your father's madness, and now that he's unavailable, literally trying to drive YOU mad.
You win by cutting her off, imo, not by confronting her.
It will exasperate her and she'll ratchet up her efforts for a while, but when she really, really, really catches on that she's encountering a new and high and well-built wall, she really, really, really will leave you alone.
What HAS to happen first, imo, is not her stopping bugging you. It's YOU stopping allowing her to, by:
--speaking to her on the phone
--letting her in the door
--reading her letters or receiving her emails
That's it. You CAN stop doing all of those things, you really can.
I think it would help you a lot to focus on THOSE THINGS as your goals. Those actions that you can take (that don't require one thing about her to change). These actions ARE possible goals, they're achievable, and you can do it, and they and only they really will completely heal this situation.
You may always carry some sadness, but you do not have to live with rage.
That would be letting her curse carry on in you.
And beneath all that, the deepest thing, I think, is you letting the sweet air in to your mind where you sit in deep listening to this thought: you do not deserve to carry on this sickness. There is no diviine or genetic blueprint that requires it of you. That was just brainwashing, and your brain is waking up. You are smarter than habit. That kind of toxicity is really just...a habit. You do not have to accept the legacy she is trying to hand over to you.
And I don't think you will, not for a moment. You are an unusually brave person already. It's the people who truly seek help and change who come here, for the most part...I know you are one.
You are brave enough to change those three behaviors in your own life.
(Her nature and her issues and her own destiny are her own. You can let go now. It's safe to liveyour own life.)
love,
Hops
