Are these facts that i have regarding love?

Okay, erm.... I feel normal being with the other normal girls but when I'm closed to this girl (my crush) my hands become sweaty and i can't even make eye contact cuz everytime i look at her i'll immediately turn some other way round O_O .... We've been in the same class for a year then we switched classes this year but we seldom talk between each other becuz i was too shy to even you know what -_- any advice is greatly appreciated! well just to ask you guys out ^^ thanks!
