How do I explain how I feel about her?

Ok, so I'm 14 and she is 13 (Her name is Delaney). I like her a ton, and I was talking to her best friend about her. Her friend asked me to explain how a feel about Delaney since I am always talking about her. I told her this: "On a scale of 1 to 100, probably like 1000." Which she replied: "That's not good enough." What do I say? I don't want to mess this up since I have never had a girlfriend before.
