HELP PLEASE!!

I got n assignment due at eleven tonight… i was being nitpicky with the volumetric fog and didn’t like wherte it was going so i closed unreal and took a break. when i opened it back up again everytyhing was F@#kKEd. there is a an error all over saying that i’m using a sky mesh but it doen’t reach this part of my screen and everything is gone… it’s in the outliner but i cant move or focus the “F” [lol] to them. all maps are toast. i found the auto save files but there is nothing in there that unreal recognizes as a project… any one here got a cape and can swoop in and save me from this train???
