Yes, and my personal view is those notes were written on purpose to present a tortured and broken narrative for the defence.If you look at the context of her notes, it would make sense that she felt the net was closing in on her and that she would spend life behind bars. I’m not saying I’m right and you’re wrong, there’s the possibility she was feeling genuinely that she had no hope of marriage or family because she was “terminally single” but the logic behind that doesn’t really fit in with what else she’d written in her notes. Have you read them all?
Obviously that backfired quite spectacularly but narcissists and psychopaths are like that, they're arrogant entitled bleeps and don't believe people will see through them.
