Listening to your aging body talk is hard

Warning: Negativity ahead! I'm till having health issues related to the hiatal hernia repair surgery. Went in for an endoscopy yesterday and they found several growths and biopsied them. I won't hear back for about 10 days they said. I'm concerned. There's always a niggling concern of a recurrence of cancer in the back of my mind. I know God's in control and I'm doing my best to trust Him completely but sometimes, that little prickly voice of Satan whispers negativity to me. I try to tune it out by focusing more on the Word. When I get all this junk straightened out, I'll have the knee surgery. I'm barely able to walk now and have started having hip pain a good deal. If it weren't for a special off loading knee brace, I wouldn't be able to walk at all. It sucks getting old. God's been teaching me to look for the positive in the negative lately. I don't know if I'm a good student or not. It seems He has to keep emphasizing this mess...
