Update:
Today they plan to discharge dad to a local nursing home (only 10 minutes away from our place) to do more physical therapy. The biggest issue we're having now is his appetite, even though from what I understand it's kind of normal to lose appetite after surgery. But overall, he's still in pretty good spirits and we are optimistic that everything will be alright!
Continue to pray for him and also keep me in prayer. Sometimes it feels like a strain trying to take care of both parents, work and continue serving at my church, but I believe it's all going to be alright!
