Chantal lies so much now that I can't even tell what's true, what's exaggerated, and what's made up from whole cloth. She's so dumb and crazy that she can't keep any story straight, including true ones, because she compulsively adds falsehoods to any account of real events. She's accidentally gaslit me, and I get the feeling she's gaslighting herself - she's dwelling in this Groundhog Day threatre-of-the-mind where plans equate to actions and nothing she doesn't like can exist, including to herself.
She's always been like this, to a point - fabricating stories, hiding pizza boxes so they're out of her mind, small efforts to try to control reality. But these days, unless she explicitly depicts it in camera, any claim whatsoever she makes can just be dismissed out of hand, because there will never be any evidence of it happening and she'll never mention it again. Exempli gratia: this week she said she was getting a singing lesson, which she's been rabbiting on about forever. She gave an extremely implausible description of the lesson plans, announced she was going, and then we never heard about it. Did she make the whole thing up? Did she just not show up to the lesson? Did she go but not like it? Did she go and forget because she's insane? Will she go back in a week if she did go? Will she mention it THAT time?
This is what I mean. It's impossible to comprehend her behaviour lately because she's just so batshit that even she doesn't seem to know what's true. They're not calculated lies like Amber's, either, they're just zero-effort attempts to delude herself and others into believing she's something other than a lunatic with no friends and an extra-wide coffin on the horizon.
