When did she ask for money? She mentioned how much she needed and that it would be nice if people helped, but she was reserved in her posts about actually asking. It was her 'Angels' that were asking people to help.
If you read many of her posts, you can guess what is wrong, and it appears, to me at least, that the reason for the Mexico trip was because that was the only surgery she could afford with what she had left.
Personally, as one of her biggest contributers, she hasn't told me what is wrong, I don't feel a need to know what is wrong, and respect her privacy on this issue.
