Tomorrow morning she goes into surgery for a total knee replacement. She is TERRIFIED

I don't know whats going thru her but I've never seen her like this. Every phone call (and I talk to her several times a day

) she crys. I'm having a hard time being strong for her. It breaks my heart to hear her cry.
She's been through alot. I can't count the many times I've been here asking for a prayer for her.
She's had a finger amputated due to cancer. She goes what seems, once a month to have spots removed.
I didn't post about this, but she just also went in and had two cancer spots removed from her head. One of them they didn't get it all

So after this knee surgery, she's scheduled AGAIN, to go for yet another surgery on her head.
I'm trying to be strong, I know I have to for her. I have to work tomorrow but will be taking a couple hours off in the morning to spend with my dad while she is in surgery.
Please, if you think about it, keep her in your thoughts?
Thanks
