My Xbox one world dissapeared!

For the Xbox One I was playing on my world I had for about 5 to 6 months now and I was flying around on my world trying to do the map room acheivment. Then my friends asked me if I wanted to play Halo I said sure so I saved and quit my world. Later that day when I got back on my world that I worked with my friends to make a entire city just vanished I was panicking because when I logged in it asked If i wanted to play on the cloud or console i clicked console because that's what I saw my dad do when he gave me an xbox. So I tried going into my storage on the game. Nothing. I restarted the xbox. Nothing. I looked up how to retrieve worlds if it happens because of corruption by uninstalling the game restarting my console. And Nothing. I dont want to restart because I did months of work and all of my achievements I earned from that world. So I beg you guys to say there is somthing I can do on that world. P.S if not is there a way to choose the cloud so I can see If that can bring it back.
