What a strange exchange! And the moral of this story is - Always make a back up. If not of your entire computer, which we all should but I bet few of us do - then at least copy the stuff you want to keep - photos, etc. onto some form of external memory. (Same goes for photos on your phone.)
What would I have done? I'd have assumed there was some way to recover or bypass the password, and asked around. I think I've heard the BIOS method before. But my computer - Windows 7 - actually allowed me to set a prompt for my password, e.g. "Cat's Name." (Just an example. My password is not my cat's name, it's far more complex than that. I don't even have a cat. Or a Harley.
