I had a similar problem when I was in high school. I liked a guy who had all the same friends as me. Everyone knew I liked him, he said I wasn't his type.
I was never afraid to face our friends, though. They only felt bad that he didn't like me back, since none of them actually knew that. They honestly thought he did.
Really, you don't have anything to be embarassed about. You liked someone who didn't like you back. It happens all the time, and I guarantee you it's happened to all those people you don't want to face. So, don't worry. Nobody will think badly of you for liking someone!
