Keep praying for my Pop, please, won't you?

Me, my Pop, and Manita

Pop's having a hard time, health-wise, lately. I don't enjoy seeing my Pop as a frail, grey, shaky shadow of himself. It's just not right. If you're the praying type, I would really really appreciate it if you'd pray for my sweet Daddy. His myeloma isn't active at the moment thanks to the stem-cell transplant from his brother, but now he's battling Graft vs. Host Disease and something else that's invaded his GI tract and is causing terrible havoc. He needs to get his energy and stamina and oomph back.
