I'm not sure how to link to another thread here, but if you run a search for Home Alone after surgery, it should pop up. It's a compendium of tips and tricks from those of us who went through it. You might find something useful there, or you may have your own tips and tricks to add. For me, the rule was that you have to make a lap around the nurses station and do stairs before they release you from the hospital. I requested that I be released on day 3 (surgery being day 0) instead of the evening of day 2, as I would have had to deal with a flight home after that. The PT said, "that's simple. We just won't do the stairs on day 2."
I had a friend pick me up at the airport, do some grocery shopping for me while I sat all lordly in the back of her car (leg up), and deliver me home. I had friends who helped me out with shopping, and came and did a cooking spree for me, and others who've brought me bags of ice. (I'm going through a bag a day for my cryo-cuff.) So even though I've been on my own here, I've had help, and that made a huge difference in relieving stress for me. That's why I thought a rehab facility might be worth considering. I would have been pretty miserable without the extra help. OTOH, I live out in the country, so I can't just make a call and get groceries delivered, etc. Each situation is unique, and the more on-your-own you are, the more you just have to plan around it. I'm sure you'll figure it out.
