Recover overwritten CSV files with multiple worksheets

- I have a CSV file with one worksheet. - After editing with Libre Office, I saved it and opened it with Libre Office again. - I created a new sheet in the Libre Office. - I saved it and opened it with Sublime Text. - I couldn't see the data from both sheets. Still, I edited in Sublime Text and saved the .csv file. - I reopened the workbook with Libre Office again. All my previous worksheets are lost. Only the last worksheet is remaining. I have been working on the other sheets for almost the past 10 days. All the work seems like it's gone. Ultimate frustration :( Is there a way to restore the lost data?
