i´m interested in somebody online plz help me!!!11

recently i feel something weird, i feel the urge to talk to somebody i know online but i get a bit shy when i try to talk with her (yeah, is a girl) i mean is like when you have a crush, i really want to know her more and be friends, not in a romantic way of course, but she seems to be nice and gentle and we have a lot of things in common, the only bad thing is when i try to send a message, i feel i´m just annoying her and i get shy and pretty anxious.
