You provided a link to your Wordpress blog, so do we assume you were using Wordpress itself, or some Word Processor installed on your computer?

If you were using Wordpress, try a test. Create a new blog, different name to the one you have lost, then save it. Watch the process carefully to see how and where it is saved. Use that information to search for the one you lost.

The same with any word processor.

I note you said (in the blog), that automatic backups were done. How is this done and where does it save the backups?
