Help Me!!

There's this boy that I really like and everything about him makes me happy! We sit together in English and he always seems to make me laugh out of nowhere and in the short amount of time of being back at school I've already fallen for him. My friends think I've gone mad for this because our groups don't mix and they always have arguments with the each other. But me and *S* get along so well and it's a shame that our friends can't be civil with each other. Another fiend of mine says he likes me too but I'm to shy to say anything, what should I do?!   (P.s I'm 14)
