Depends on the bet. If it's "Did she do this to herself?", I'll take the bet. She didn't.
If it's "Is this story true?", I won't take the bet. It's not.

I'm confused. You think she didn't self-inflict, but her story is not true. So somebody else did it to her, presumably with her consent? Perhaps some of her "sisters?"
Actually, that is quite likely. Among other reasons, it is obvious that she held (or was held) very still while all the cuts were made. That is highly unlikely given the story she tells.
