FL not only has burnout, she is definitely depressed, and now she's in a foreign land on her own where she's basically a huge disappointment who at any moment be discarded. She might as well be a political prisoner lol let her have her depressive episode.
Also, totally unrelated, but while he IS trying to get her to eat for her own good, just for the real people out there reading this... threatening group punish of others for an individual's actions is a psychological tactic that wont help her depression, in fact when used on prisoners it is recognised as a war crime under the geneva convention.
