Yes, ma'am, to all of your post, and especially the above.
I think Brandi isn't clean-handed when it comes to LeeAnne. Brandi's "insight" ("LeeAnne just wants to be pitied") is such a derogatory dig (it paints LeeAnne as wanting something unsavoury). The thing LeeAnne craves (the thing most abuse survivors crave) is empathy/validation (not pity) but Brandi saying that wouldn't allow her to not-so-subtly shade LeeAnne as worthy of contempt. I also think Brandi wants empathy/validation herself; she pointed to herself as an example of somebody who doesn't talk about her own history, but I think she'd love to do it more (if only to shut LeeAnne down.)
And even though it bugs me at times, I think LeeAnne not shutting up is part of why she's intriguing in this group - she's crazy, selfish, vulgar, etc, but there's a refusal to abide by the lady-rules that say women need to shut up when they annoy, bore or piss people off. There's a gritty stubborness I find interesting. (And that flesh-eating bacteria line - and LeeAnne's delivery - was the only time I laughed - I give her reality tv points for that.)
All that said, I agree with everyone who thinks LeeAnne needs real help. The repetitive invoking of abuse seems (imo) to be a compulsive ritual in pursuit of validation and empathy (not just attention seeking, or used only in deflection - it's also that, but not just that). I think the ritual has real meaning for her, but it's also hollow. It's like emotional junk food - it doesn't feed her in any real way, and twenty minutes later, she's raging, invoking or crying about it all over again. She needs a great therapist to help her understand that her feeling unmoored - not belonging in this group, not belonging anywhere - will only be healed when she finally looks inward.
