Easy dessert, or poignant, realistic portrayal of woman's downward emotional spiral?

Well good gracious, if this isn't one of the most disturbing little bits of "advertising" I've seen in a while. A 1950s ad for, of all things Jello pudding -- is there a happier dessert? I'd thought not, either, until I saw this horror that manages to actually demonstrate what a psychotic break might look like if it were to happen near dinnertime. In 1952.
