Text disappeared from document, is there any way to recover?

Today when I started to work on my document, i noticed that only the first 10 pages were there, the rest was gone. I may have saved the document before I realized this. How do I find the content that is gone? I still have the file, there is just not much in it…

I worked in LibreOffice on mac, with a .doc document. My LibreOffice is not set to save versions (i did not know you had to change this setting yourself), and I do not have time machine.

I am not sure why the text dissapeared, but there seems to be other problems with the problem as well. It can not be opened in OneDrive or Google Drives editor.

Is there any way to find the missing text?
