My little grandson feels your pain :-) . He broke his the day before his birthday in December . His shiny new bike is still unridden and he cannot play sports, go in the playground or ride his bike until March as he fractured his growth plate.
I asked him for tips - he said- and I quote :-
1. Mummy will wash you ( but its ok to be grubby lol!!)
2. Ask your best friend to come over to play
3. Its ok to wear your pants for 2 days if getting them off is tricky but don't tell Mummy.
4. If you say it hurts people give you ice lollies and such.
Seriously , I feel for you , nothing worse than being incapacitated when you are raring to go. Exercise wise , maybe walking is the best you can do for now? Decluttering can wait ( no matter how much it will bug you ) .
I think covering it up with a plastic bag and showering is the easiest solution for personal care and likewise choosing easy clothes just for now. It will improve of course but you just have to get through to that place.
Hope I at least gave you a smile x
