That's a little concerning on a lot of levels even without the cult notion. I mean, she's not an octopus, or a mother, and I'm hoping she isn't starving herself to death.
I don't think that's over-reacting. You think there's something going on with it? Like... cult something? I can pull out some books and do more specific research and see if we can figure out if it is actually something to be concerned about.
