Please tell me how to retrieve my data.

To restate, I pressed the, select all button, then the justify button. The screen went blank. I pressed the, undo, button. Nothing happened, so I pressed either the, save, or, don’t save button. I turned the lap-top off yesterday morning, and I’m afraid I shall have to repeat that month’s work. Any help to retrieve lost work will receive a thousand thanks!

Furthermore: This is a duplicate of I had a 200,000 word document that I tried to justify. I pressed the justify button, and all my data was eliminated. What to do? and if you want to enhance the details of the question, edit that question and don’t ask a new one. Thanks in advance …
