Hello there! I am sorry to hear about your ankle, truly. It does not have to be a dramatic event to make the injury traumatic to our mental state when it comes to being active.
Last time I had an injury it was a relapse of my dislocated knee, which has about the same recovery time as a badly sprained ankle. I would recommend listening to your body, as cliché as it may sound. You will lose some progres, but not as much as you are fearing. Once you are healed, start with some stretches for your calves specifically to get the blood moving again, then go for a light jog for as long as your ankle is ok. Once you feel even the slightest discomfort, stop jogging and walk. Do not stop moving suddenly and all together unless you really have to. Try to keep it moving. Then start the app back up where you left off, repeating the day until you are back to where you were. Good luck! Let us know how you aredoing!
