What should I do if my crush knows that I like him??

I have this crush in my cl and he's a bit shorter and younger than me..... :( I just met him at the beggining of the school year and ya. My friend told me that my crush told her that he knows that I like him.. Damit!!!! I don't even dare take a look at him when he is near me. The only time I get to talk to him is when I go to my friend desh and hit or slap her on the face for reason. I get super shy when I get near him since I think he knows I like him. ALAM MO NAKAKAINES TALAGA !!!! CHE
