I sprained my ankle 6 weeks ago and am still having a good amount of pain. I work as a chef in a nursing home. Is my career as a chef over?

I work 8 hours a day on my feet. I am not allowed back at work until my ankle feels as it did prior to the fall. I was walking down some steps and hit the patio stone on the edge where it was uneven. Most days I can walk and have no problem but swimming yesterday really made it irritated.
