Recover replaced file in Pages

I had two Pages docs open, and wanted to change the name of both. One was called "[Word]" and the other was "[Word]-[Other Word]". I changed the first one, then went to change the second, but accidentally only typed in "[Word]". It did pop up a window saying there was already a file with that name and asking if I wanted to replace it, and I, being a total idiot, thought for a sec it was asking if I wanted to replace the NAME of the file, so I clicked replace. And you know what happened. It essentially disappeared the first doc, and now all I have is the second. And the first doc was huge and had taken weeks. And now it's gone. I tried to revert it to a previous version, but the first doc isn't in any of those versions. I tried iCloud recovery, and it's not in there. I do not have a time machine backup already done, because I thought iCloud was enough. Is there any chance at all of recovering that first doc, or is it gone forever? Please don't tell I'm dumb because I already feel like the dumbest person on the planet.
