Writer's Fallout Shelter

Ok, I am writing a story...as is pretty much everyone else it seems. I have all my writing on paper that I transfer over to word when I get a nice stack. The problem that I have though, is that I kept all my notes on timelines and house lines, minor characters, and full histories of the major characters in the computer, and it just crashed. The hard drive is not salvageable. With that much information, it makes me wonder if I should even continue. The notes that I kept helped with continuity and a lot of other things, and it makes me wonder if I should just give up on the story since a lot of it is just gone. Suggestions please
