Good points, only you may consider a more specific argument, that being the nature of the self destructive behaviour. I would suggest the particular behaviour is bulimia. This is strongly suggested by "charcoal" or blackened teeth. Fahion victims follows logically as the victims of bulimia. The bullshit fakers and enchanted kingdoms are the respectively the modelling industry and department stores. Models usually have naturally high metabolisms, which they don't tell overweight women, and thus they are bullshit fakers. Department stores can almost take people off into a fantasy land of sorts, and that suggests the metaphor I put forth.

In the beginning of the song, we see the lines "My reflection: dirty mirror/ There's no connection to myself" The meter is trochaic octameter suggesting a religious element, as though the narrator worships the mirror, but it does not connect to the thin figure being reflected.

In the bridge, the narrator rants, "emptiness is loneliness," so he needs food to fill that void. "Loneliness is cleanliness" suggests that when he eats, he feels dirty. Then he says that "cleanliness is godliness", implying that once he is empty again, by purging, he will feel powerful.
