I am inlove? Be as good in my classes.

There is a girl in my class that I do almost anything just to get her attention . I don't know what's wrong with me , I have add her on my Snapchat and all the posts I post are directed to her without her knowing that . I don't know if I love her or I just like her but seriously she is the only thing I look at in the class . I turn around like 100 times just to look at her and impress her . I am a girl too , I don't know what this is honestly. I talk in a certain way just for her to hear me or pay attention to me . I get so hurt when she walks with other people but me. When she talks to me I am the happiest that day and I just think of our conversation all day long . She is really attractive and smart .... I tried to stop thinking of her and getting her attention but it's hard . I also just study because of her , I want her to know that I am all smart and all . If she wasn't there I wouldn't be as good in my classes .
