I finally read both books (HP to see what all the big deal was about, Twilight because oif a dare) and I can securely say that Bella Swan needs a psychiatrist of some sort. Really, I'm not a qualified proffesioanl, but I can diagnose her with a few disorders just off the top of my head.
Also, Have fun. Go down to the "The 'vampires' of Twilight are not vampires, but..." WMG and read it. (Don't click on any of the links, though, you'll be there for hours on end).
