Admin panel????

Hi,

I know this is going to sound really simple or dumb but I’m really not getting this. Maybe because it’s 2 in the morning and my brain is fried but either way I hope someone is kind enough to help without mocking me…

I just installed the latest version of WP to my server on BlueHost. Now I’m wodering how I edit my blog?? I previously had a blog on WordPress.com. The username and password I got after the WP.org installation was complete is the same as my wordpress.com info. I’m wondering if that is hurting me because the administation panel looks the same and offers no flexible options WP.org promised. Someone please help me and let me know what I’m doing wrong!
