You put it so bluntly but yes, you're right. She's very insecure and empty inside, and she senses it. Why else she'd live in a chateau, have all the parties and act like a fun teenager but to ask and try to be worthy of friends and their acceptance? It's beyond sad, all the begging and tricks she pulls for adulation and trying to be more extravagant than anybody else just that you notice her. She needs the confirmation constantly to feel accepted. Having an absent overindulgent father and neglecting cold mother has turned her into a narcissist. But the damage is done and there's no cure. I have some empathy for her as well since we know why she's transforming her not so grand salon into a fake shell of Versailles, just to impress us. Nevertheless, we must remember the old rule to put our own oxygen mask on first before helping others, being around her is like second hand smoking, you'll get sick eventually.
