Made a Domain Name change, Now my website is messed up.

Rookie mistake.

Long story short, my previous domain name was lconstelle.com, I decided to change the domain name to roseazanero.com (tech support at Host Gator helped me do this), now when I try and visit my website, it’s there, but the theme I had is gone and the website just looks horrible.

Worst of all, i can’t even log into my previous wp-admin login (lconstelle.com/wp-admin). Now it says it does not exist. I made a big mistake, anyone have any idea how I can resolve this?
