My mom takes a whole host of pills for everything under the sun, more than just an anti depressant. I am pretty sure Tori is doing the same. Her behavior is just SO BIZARRE. The pouty lips, the twitching, the unnatural response to everything Dean says, that (not on this show, but unforgettable) GIANT tantrum she threw with stella on the bed, the acquisition of warehouses full of stuff and animals. Yeaup, seen all of that in someone with serious mental illness my whole life.
