Lost Photos

I spent about an hour working on pictures of some of my new jewelry, downloading & editing, trimming and culling.
And I just lost all the pictures. I have no idea what I did, or if they're really completely gone. I'm too upset to deal with it.
Arrrgh! I don't know what I did! I was trying to rename the folder, 'cuz my stupid program only lets me keep them filed under dates and I HATE that. And somehow I clicked once too many times, or hit a wrong button. I've never done this with a whole folder of edited and ready-to-go pictures...
