Lost my CODE!

I was finishing my biggest project yet that I worked on for 2 weeks and… my computer powerplug screwed up and my system shut off. I havn’t done any recovery or back ups and the class I was working on completely disapeared. It was as if the text was invisible, because I can highlight it. I was going to release it as a WIP today too D: :’( . Deep down Inside I know I put in a LOT of work but for some reason… I’m relieved. I’m so speachless… is there any way I can revive it? I checked my workspace. (Does the fact that I’m using windows 8 help me?)
