Its almost like Japan and the idol/model idustry has a history of overworking their performers and etc to dangerously low levels of mental health lol. The love putting too much pressure.I understand wanting to push through, and all that but given how much all this is affecting her, maybe just:
A, Debut as a ntow-completetly-twig figured model, or
B, as TL noted try to seek a therapist or some other form of mental assistance.
In just general, this much pressure, especially against something you don't have full control over is not great for the mental-health department.
