HELP! Accidentally hit "don't save changes"

I made a grave mistake and closed a file and accidentally selected "don't save changes". I know about the Recovery folder which saves in-progress versions of the document in case of the program crashing, but my understanding is those files are deleted once you save (or, in my case don't save).

Is there ANY way to get back to a previous version of my file before I accidentally closed it without saving the changes?? In panic mode that several hours worth of work just went down the drain
