Prayer for healing my sick Grandma

Dear Lord,

Please help my Grandma right now, as she is in surgery, which has an extremely high mortality rate.
Please guide her through and heal her, please make sure she gets through the surgery well and makes a full recovery.
Please Lord I need this woman in my life, she’s not well but I need her. I can’t go through life without her being by my side. I love her.
You are the only one who can help.
No-one deserves healing and well-being more than her.
Please Lord, help.
