She has been fighting cancer over the last year or so.
She had some kind of surgery back in late Nov early Dec.
The older we get the harder it is to get over surgery and it's takes longer to heal.
Recent posts on her Twitter account seem to indicate that she is recovering nicely though.
Thank you for the information. That makes sense. I’m usually not one to speculate based on appearance, but it seemed apparent enough to me that something was wrong that I thought I’d ask.
Hopefully she continues getting well.
