Sounds like a huge case of cabin fever to me. Also sounds like a big case of pay back time for over doing it kiddo. You saw what the price is. Did you forget the second biggest truism here: You have ONE chance to heal properly, don't blow it.
You are asking for activities to keep you occupied. So I guess that means you have already gone through what ever it was that kept you occupied before surgery? Were all your activities physical ones? Roller blading rather than reading?? How about these?
1. Go out, meet some friends for lunch. Even if they are working they must take a lunch break.
2. Play some games on the computer. Surf the Net. Go to www.aj.com
and type in a question about a place you've always wanted to go and read about it.
3. Get out and visit the library.
4. Go to the zoo, they are open during the week.
5. Go to a mall, buy a big pretzel, sit and gawk at the people going by.
6. Get a notebook and start a journal.
7. Visit a card shop, write some notes and send some real snail mail instead of e-mails.
8. Go to an aquarium shop and buy a gold fish and a bowl, take it home and watch it swim around.
9. Go to a park and feed some ducks. Take a drawing pad to the park and sketch the ducks.
10. Go out to a music store and listen to some music, buy a new tape or CD, go home and listen to it while resting.
11. Take some cookies to a rest home and see people who are really cooped up and can't get out like you.
12. Go to a metaphysical store or music store and get a relaxation tape or CD, something with guided imagery on it and take it home and chill out.
