4 weeks is a long time to be home. My friend Joey (who graciously visited me in the hospital and called me several times afterward to check in) asked me if I was getting cabin fever.
My answer to him, oddly enough, was "No".
When I started to think about it I found it really interesting that I didn't feel like I had to get out at all. There have been times when we've had a freak snow storm that left us 'trapped' at home for 2 or 3 days and we couldn't wait to get out.
I think the difference is that I knew I was physically unable to go out and do anything. Initially I had a lot of pain, and for even longer I had very little strength or stamina. Even simple tasks like taking a shower left me exhausted. So I'm guess that's why I never had the feeling of cabin fever.
So, what did I do at home for 4 weeks? I watched a lot of TV and movies. Toward the end of my time at home I resorted to paying for on-demand movies because I'd watched everything of interest on the cable channels and the premium channels we get.
Also, I slept a lot. I'd go to bed at 10pm and sleep until at least 9am.
Then there were the occasional mid-day naps.
