Prayer request

Well, this Christmas was good and we have so much to be thankful for however, my grandpa is in the hospital again and has been there since Sunday and has a long road ahead of him. He went in w/ chills and a temp of 103 degrees so they thought it was some sort of infection and it is. He has a blood infection, kidney infection, had renal failure, heart failure, and now has thrush in his mouth (a yeast-like infection) as well as he has more fluid build-up; which is an on-going problem with him and why he was admitted not too long ago; they just drain it off but now it's building up a lot faster. He is on heavy antibiotics and doesn't look good. He will be in the hospital for at least 10-14 more days for them to monitor him.
He told mom today that he was tired and ready to "throw the towel in". His wife, my grandma and mom's mom, died 13 years ago Dec. 23rd so this time of year is tough on him and mom as it is but he's 91 and has gone through so much. I'm not ready for him to go yet. He's always in good spirits though. No matter how bad he feels he's always in good spirits and funny. He is so excited about this baby and we even took pictures to show him all the ultrasounds on Christmas Day. He was even cracking jokes then saying "he can see how much Baby Kee looks like me." haha...that's something that always makes me feel better but I know he's so sick and is tired but PLEASE pray for him. His name is F.M. (yes, just the 2 initials and i don't know what they stand for, haha), F.M. Butler and he's my grandpa whom I love dearly. Just pray...
~God Bless
