I still fail to see how, unless your up to the eyeballs on painkillers, a mentally demanding role has got anything to do with preventing a broken ankle from healing.
Taking aside, as you’ve said, any issues with mobility etc.
You are contradicting yourself. Is it that your job won’t allow you back due to your physical limitations or is it , as you’ve said previously, that you feel the mental demands of your job will somehow stop your ankle from healing.
Sorry but if a member of my team came to me with the above reason I’d not be too impressed.
