5 hours wasted

I just spent 5 hours doing an English paper. I did it once, was about to print it, and then what does the computer decide to do? It decides it's going to play games with me and shut down. I got it running again and pulled my paper back up. It shut itself down again. When I got it back up AGAIN, guess what WASN'T SAVED? My English paper. That's what. So I spent another three hours redoing it from complete scratch. I'm so ticked off it's not even funny. And since it's midnight here, I do believe I'll be off to bed now. I can at least get five hours of sleep in, can't I?
