First off, just knee surgery wipes you out. I slept so much, it was unreal. I never sleep in the daytime until I had the surgery. It is very traumatic to your system, and you just need time to get over it. Secondly, you didn't just have knee surgery, you also had pneumonia which is a huge, HUGE drain on your system. My brother had pneumonia when he was a young and healthy man, and it took him weeks and weeks to get back to normal. I'm surprised you're able to lift your head. The only things you should be doing are the necessary ADL's, and some easy therapy for your knee. Rest, rest and more rest is what you need. When I get back to Homewood, I will be tickled to death to help you with anything else you need (shopping, cleaning, laundry- you name it.) Until then, get your nurse cousin to pitch in and help in a way that really helps instead of making you feel guilty! Don't feel guilty!
