how to recover a document

HELP PLEASE!
I did 5 hours of work on a an assignment before Christmas which is due next week i have auto save and backup turned on and i always manually save before I exit libreoffice just to be sure but when i went to open the document today it had a crash error notification popped up and proceeded to recover my document only it didn’t recover any or it that i had done the last time. After doing some research I followed my backup path and there were no files I’m absolutely raging here all help appreciated!!!
