Well today I did the stupidest thing

I went to play ball with skate shoes on -.-
Well i jump for the rebound and..boom..Byebye ankle =/
Ima stay with a cast for 3 weeks (doesnt seem alot..but i can barely stay 3 days without bball..) and then I need to do Physio Therapy (no idea on how to spell/say that in english -.-)
Any1 passed through this and wanna giveme some suggestions on how to keep away from ball for 3 weeks?
Ahh i need help!
