Improvement every day

Today, it is exactly two weeks after my operation. I am still not allowed to put any weight on my foot. The strings were taken out two days ago and since then the swelling has gone down very fast. But take a look for yourself:

I am really sick to death with laying around all day long, putting ice on my foot and needing 20 mins to "go" 5 meters. Well, I am a good girl and following the instructions of my doctor very precisely. So I will be bored as hell soon. :( If this is not the case, I guess I will fly in pieces since my mummy is taking care of me. So the food is good and I am not moving at all. That's a really bad combination!! I already have gained 3kg. :/  So I should start doing some kind of sport. Any suggestions?
