I just spoke with Shelly's sister.
They're keeping Shelly sedated, unconscious and on a respirator for the next 24-48 hours, maybe longer, to allow her body some time to heal without using any energy. Good news is that the doctors think it's working. According to her sister, she's doing much better than she was last night but she's still not out of the woods. All that's needed right now is thoughts and prayers. She is going to keep me updated as much as possible and hopefully next time I talk to her, she'll have good news.
I'll update (or Kim will) as soon as I hear anything.
