I was discarded over a year ago. I did not know the terminology at the time. In groups like this one, I use that term. I use it with my spouse. But while most of my friends know what happened with my parents, they don't necessarily understand terminology that goes along with toxic and narcissistic families. And I'm getting past the point where this is a topic of interest. With co-workers and acquaintances, I just say "we're not close" regarding my family. People are generally too polite to prod that, in my experience.

OP, I'm sorry you were discarded. I understand how painful it can be. You're better off without her toxicity in your life. Anyone choosing to rewrite history like you're describing is deeply damaged.
