If anyone had, it would not be very discreet of them to discuss it here though would it? If she were telling trusted regulars what had happened, then I guess you are not one of them.
If she isn't, then I guess she doesn't want to tell punters her personal issues, it's really none of our business other than to wish the lass a speedy recovery, well as speedy as possible if like you say she hasn't been available for months.
