blog is visible online and can't access admin

My website is hosted on GoDaddy. The blog is linked to the site. I can view the blog no problem. My user name and password don’t work as the admin and I can’t figure out how to fix it? It’s like my user name never existed. When I type in the user name and click the “forgot password” link it just refreshes the page like it didn’t acknowledge the request and I never receive any kind of notification that WP even received my request.

HELP PLEASE!!!!!
