Messed Up my Blog

Hi .-. As you can see my blog looks really different. I changed the template because I got tired of the old one. Turns out this one looks freaking horrible and I like the other one... But I didn't save it. I didn't save the other template so I have no idea how to get it back. My dad'll help me but he still doesn't know of it would be the exact same. :( I miss the old one.... I might not post for a while because I'm trying to fix it... :/
