Welcome!
Congrats for getting away!
You didn't cause her issues.
You can't cure her.
You can't control her or change her.
Her blame game is classic addict and you can just imagine a duck saying, "Quack quack quack." It means nothing.
I'd strongly recommend Adult Children of Alcoholics and/or Alanon for you! You'll get a ton out of it.
Stick around!
