Not that I don't agree, it was certainly an overreaction if it was suicide...however, she probably felt completely humiliated and since this thing went completely viral, she probably felt so stupid that she fell for it. On the flip side, had she not fallen for it and it was literally the Queen who called in and she didn't provide answers to her questions, she still would have been publicly humiliated.
I feel bad for her either way. She was put in a really awful position. I don't think it warrants offing yourself, but maybe there were other things going on in her life.
The UK media really fuelled this whole thing. It would have been forgotten about if it wasn't for the way the media bangs on about this kind of garbage.
