Haven't Been Able to Access Blog For Months

I am a total beginner, entirely clueless about code & hacks and whatnot. I set up a WordPress blog through Godaddy and now I can’t access it. I get a bunch of e-mails all the time saying I need to moderate, but when I try to use that same e-mail to find my password I am told it is not registered. I have no idea how that is even possible when I continue to get messages that I must deal with my blog. Please give advice, I am clueless.
