I don't disagree with what you've said, but: Moving right now probably isn't an option, especially if she's low on cash, because for her to get out of her current lease she would likely have to pay up two months rent, and she'd then also have to come up with the money for application fee/deposit/movers to get into a new place. If she's behind on rent where she is now, I'm not sure how that will reflect on her when she applies to move elsewhere (if that can even be checked, that is).If she can, she should try to reduce her expenses by moving in something cheaper, returning or selling her $6k bed, cooking at home and reducing consumer purchases. Will she? Probably not. Acting as nothing happened is not going to help to change the situation. She will need to be more creative on her channel and find a part-time job that she can do at home. Staying off YT is not a solution for her.
Also, if she reduces consumer purchases AND refrains from doing mukbangs, she has literally nothing to film, apart from cooking videos, and those never go over well, so she probably won't want to do that. I'm not sure what she'd do without YouTube income, but if she's not making money, it's unlikely she'll bother to upload.
