[Wordpress issuses] bettinaruiz on "Changed log-in settings by mistake. Anyone can help? It's rather urgent!"

Hi,
I have a serious problem. Yesterday I set up a gravatar in my blog http://www.blixenlmujerdelaspalabras.wordpress.com. For some reason I must have logged in incorrectly and now when I click on the gravatar on the right side it links me to another blog (bettinaruiz'sblog) I created a couple of years ago and I didn't even recall I had. Therefore, I cannot manage my current blog blixenlamujerdelaspalabras.wordpress.com. What can I do to reestablish my former identity, so that I have access to the blog I'm using? It's quite urgent...Thank you!

The blog I need help with is bettinaruiz.wordpress.com.
