I had been working on a research paper for the last week and have been saving regularly. Today, I opened the document and highlighted two rows of a table to convert to a graph, although i could not actually do it. I had the two columns selected of the table i created and i selected the "graph" option. I realized that this wouldnt work since i wasnt using Excel, so i pressed Command+Q to quit out. Now every single time I open the document, it takes me back to the previous save, which is about 7 pages back. Is there something that I did wrong? How do i fix this? I don't have Time Machine configured since i do not have a separate hard drive, which is a huge mistake when I look back.
