Suggestions very much appreciated, grrrr!

Anybody got a suggestion on how to roll back changes to a wordpad document you accidentally deleted a chunk of? I thought not saving changes would sort things, but evidently that isn't the case. I am not. happy. :(

No, I don't have a damnable backup. That would make too much sense.

Edited to add: I've been able to retrieve the most important bits of what I lost, thanks to having sent them to friends. I'm in the process of recreating the rest.

I'm also on the hunt for a word processor application that has a better backup feature than wordpad, doesn't stink for accessibility (looking at you, Libre Office), and doesn't have Google tentacles in it.
