(10 ez pts) I have a problem with girls?

How do I get over shyness. I want this girl to talk to this girl I've known for 1 month and she's giving me the opportunity but everytime I get the chance, I just crossover to the next table and talk to my friends. I really want for me to talk to her. She is soo hot man, she's Jewish lady (16) and I'm 15..
