Replying to Lost my job due to injury

Hey ns, a few weeks ago i tore my meniscus skiing, and haven't been able to ski or work for a while. My knee has been feeling pretty good the last few days, so I called my boss to say that I was able to work again. She told me they had already hired someone to fill my spot and that I wasn't needed. I don't have enough money to last the rest of the season, and I don't even know if i'll be able to ski anyways. Should I just go home? Anyone else ever had this problem?
