My Game Won't Load!

after multiple try's and resetting my device, I can't get my world to load in! 
my game had crashed while I was sleeping, and now whenever I join back into the game, it puts me into sleep mode. If I press either "leave bed" or "open chat" it instantly crashes the game. I also waited 2 minutes, and it wouldn't exit sleep mode either. Not sure what to do here, I had made a backup of the world just in case, but that was a week ago, and there's lots of things that I would loose if I went back to the older world. Please help ;(
