So something pretty horrible just happened. I was editing my TeX, and I closed the TeX file and when I reopened the file, all my previous work was overwritten. The preview pdf from TeXshop remains, but everything else was overwritten by my scrap edits.
To further clarify, I still have the remaining .aux, .log, .out, .syntex.gz files
Is there any way to recover my previous work? And no, I didn't expect it would do that so I didn't have Time Machine.
