When you are ashamed of your weight, I'm sure that any talk of diets is very stressful because it does feel like you are being judged (you probably are). Most people aren't being assholes about it, though. Some people are self-centered. They aren't even thinking about how you might be offended. Some are well meaning -- they are trying to broach the subject in a non-judgmental way by talking about their own diets. Some are the mean girl types who will take digs at you. (Unless they are coming out and calling you a lard ass to your face, though, there's not much you can do about it.) But, if J is totally, 100% okay with her weight, she should not give a rat's ass what anyone thinks about her weight. The fact that it stresses her out should be a huge clue to her that she is not happy with her weight and her body. Instead of forcing everyone else to stop talking about it, she should spend some time thinking about why she is triggered.
Personally, I think J's co-worker already can't fucking stand her, and is doing the passive-aggressive Mean Girl thing by using "diet talk" to make her uncomfortable because it's obvious that's one of J's sore spots. That's a classic female covert aggression move--use a normal topic of conversation that most people would not consider offensive around the one person who would.
Maybe the co-worker hates J just because she's a massive fatty, and for no other reason. Maybe she hates J because here's this massive deathpig who insists that she should be accommodated for a condition that is entirely her fault. Maybe the combination of a deathpig demanding respect for being a deathpig, while also insisting upon genderspecial pronouns, proved to be too much. Maybe J is already turning out to be shit at her job because she's a barely-mobile deathpig. Maybe J takes forever in the restroom when she's needed elsewhere (and destroys it every time she uses it). Maybe J spends too much time lecturing about Fat Acceptance, pronouns, and microaggressions, and complaining about oppression, and her co-worker is sick of hearing about it.
Given that J isn't very bright, and is a massive, self-obsessed toddler, I can't imagine she's very likeable or pleasant to talk to--every conversation is probably a minefield, in which one wrong step will cause offense--so there's nothing to balance out the inevitable annoyances that come from working with and accommodating an "infinifat." So I can easily see a co-worker deciding to intentionally trigger her with mundane "diet talk," just as another seems to be taking a more openly aggressive role by not using her pronouns.
Will she ragequit? It took her so long to find a job at all, and there are so few jobs she could potentially do, given her "infinifat" status. She's in Kansas, so her insistence upon genderspecial pronouns is probably enough to keep her from getting hired, even if being a deathpig was still acceptable. And given what a snit Corissa was in while J was being an unemployed drag on her, I think she might try to hang on to this job for a while.
J is obviously not a true believer. She's so close to having a break through and leaving the cult, but she'll never have the courage to do it.
If she did have that breakthrough, she'd still have to deal with her obesity, and I don't think she's mentally up to that task. She'd have to learn to consider the long-range consequences of all her actions, and act accordingly, rather than acting on impulse. She'd have to learn not to turn to food for a regular dopamine hit, and find something constructive to replace that.
J realizing that she's been utterly suckered by the FA movement--and that she was such a willing, even eager, sucker? That would take a level of self-reflection I don't think she's capable of.
And what would she get out of it? It would end her relationship with Corissa, who has been the primary breadwinner. J would be on the fucking street, or she'd have to go back to live with whatever family member might take her in. She'd still be in the same massive, ruined body, which would require years of focused effort, dedication, and commitment to reduce to a size that isn't torture to live in, and even then she'd be awash in saggy, disfiguring excess skin (which brings its own health complications, on top of the psychological issues). She's not very bright and has no particular skills or talents beyond stuffing her face and lying to herself, so it's not like there's a bright professional future awaiting her.
There is nowhere for her to go. Her life would get a whole lot harder, and in some truly scary ways, and she'd have to develop an extraordinary level of self-awareness and self-discipline to navigate that--only to end up with...what, exactly?
So I think she's in it for life--which will not be very long, and will be increasingly hellish. There will be no awakening, and if one threatens to happen, she'll just keep stuffing her face and denying it until she dies.
Yes. Im so very stressed by dipping sauces. My life is so bad that I have panic attacks over ketchup. On a serious note,
I think J is just looking for reasons to quit because it is buttmad it’s girlfriend can laze about while it has to put on pants and work.
J getting her massive ass out of bed, dressed, and off to work takes a tremendous amount of strenuous effort. There's no way it doesn't, not when you're constantly carrying four times the weight you should be, and are unable to perform basic functions--such as putting your socks on--without assistive devices. And I would bet that all that strenuous effort is also accompanied by pain from her overtaxed back and knees.
Getting up and doing that every day? Yeah, I wouldn't blame J for either wanting an excuse to quit--or maybe subconsciously setting herself up to get fired (by doing things like complaining about co-workers and workplace "microaggressions" on social media, for example).
