This happened to me just a few minutes ago. I thought I was done for and wanted to cry, but if your left click on the back arrow in your browser window up in the top left corner, you can select the version right before the one that asked you to Log in and your page with the page with your text input should show up. It might not work and maybe the prayer I said to Lord God was what saved me, but give it a try. If you end up getting access to your work, just select and copy it just in case you lose it again somehow. I hope I'm saving someone's life here.
