Sorry to hear of your mishap! Hope the pain goes quick and you will be back to fire on all cylinders.
My advice (Calamity Jane) from personal experience of various injury:
Don't have attractive food in the house - if someone else's brings the sinful stuff in, then make a pact that it is theirs and you are no allowed it. (make them feel guilty!)
A little treat is ok (but with poor will power you probably will go for it anyway) - you are injured and feeling sorry for yourself, don't be too hard on yourself, and soon you will be back in action. Go for plain/less calories biscuits or crisp or whatever rather than the worst (nicest) ones
When you go back to activity I would be careful with compensate with good side or train good side only, it may lead to long term preference on the good side.
Try acquajogging if you can't have hydro therapy. Is like running in deep water, with a flotation belt (if you are comfortable in water and not a great swimmer works well) no impact, and when you getting better you can jog in less water for a while to introduce some partial weight bearing but still gentle.
Once you are mobile if you can stand a gym use thread mills and upper body weight training to fill in the time you would be using whilst cycling to get some strength and mobility back in to you - of course if you have a phisio telling what is ok or not is perfect.
And my best pearl
get angry at being injured and promise yourself to use time wisely once you get back to health and enjoy your bike and fitness to the most. I call it plot revenge.
(the weight will go!)
Good luck!
