Only Showing Blog Options – Please Help!

I’m an idiot and didn’t understand the difference between the .org and .com sites. In my stupidity, I signed up for a premium wordpress.com blog and promptly cancelled it, realizing it wasn’t what I wanted. I did, however, keep the domain name.

I then signed up for a subscription to BlueHost and installed WordPress there, using the domain name I purchased as the domain. When the installation was completed, I found, much to my dismay, that it was still showing up as the my blog, with .wordpress.com at the end of the domain name and not giving me any access to plugins or the themes I wanted. I am trying to get rid of the .wordpress.com but keep the domain name I purchased originally, however I have no idea how to do this.

I am just hoping I didn’t screw up too badly to fix this with no financial damage. I am in the process of starting a business and my stupidity has only added to my stress. If anyone can help, I would be extremely grateful.
