Grandmama - please pray!

Most of you already know, but my grandmother (my dad's mom) is in the hospital right now with what the doctor's think is one of the worst cases of pneumonia they've ever seen! One of her lungs is totally filled up, and some of her other lung has some fluids in it as well. She also has the bacteria in her blood stream. =( My mom and dad left for Missouri today and will spend a few days up there in Joplin... the doctors gave my grandmother a 50/50 chance. : ( We all covet your prayers through this time. Thank you all so much!
