I don't think so. That might be Eugenia's case but most anachans want to be left alone to starve themselves in peace.
Anachans are hungry for social appreciation of their achievement. By nature of their illness they can’t be “left alone” since they require caretakers once they hit a certain point and they know this. They just expect people around to find their compulsion as important as they do.
Look at the vegan ginger. At many stages she seems hungry for social interaction (at least for IG content) and has joined “differently abled” ballet troupes, tries to be an ice skating coach, natural healing guru, attends various churches when she feels like it (then bails when they don’t cater to her and give her disabled parking spots), etc… Her TL is one long narrative of alienating everyone around her by being totally oblivious to everything but herself. I think this is one reason she started to munch, she gets more pity and social leeway being a physically sick wittle girl than a manic anorexic.
Eugenia, otoh, does seem to be isolating more than alienating but I think this is mostly because her mother has provided the perfect cocoon for her to do so. Once she alienated the little group of YT friends she was able to run back into her bedroom and ignore it all. Besides she gets the social commentary she craves about her physique from SM.
Eugenia has said she is perfectly content to live with her mom forever. I think Eugenia realizes she needs (and wants) a full time caretaker to be an apex anachan and her mom is fine with it.
One thing most older, survivor, anachans detail is how important it was to them to hear other people lament on how tiny, starved or skinny they were, so they don’t want to “be left alone to starve”. They do want people to stfu about them not eating, so if “stop hassling me about starving myself” is what you mean by “left alone” then sure.
Even Annachan supreme Ashley Issacs pulls her bag of bones out of bed so she can go on Lich parades in Target every so often and take selfies. She’s always sure to wear shorts when she goes on outings so everyone can see how incredibly starved she is. One of her very few motivations in life is to be seen in public by others so they can be shocked and awed someone so thin is still alive and shopping. It’s one of the few joys she has left.
It’s like that tree falls in the wood cliche. Is any reason for an anorexic to starve themself to death if no one is there to see it?
