Am I really in love with him?

[A.H]

I'm interested in someone whom I meet in my tuition classes. Yesterday I found a Facebook account in his name and i was shocked and there was a difficulty in breathing at that time too.so as I think, it's his profile. And today when I went to a tuition class and he was there. As i was not able to find the class I asked HIM about that and i was just excited. I don't know whether I have a feeling about him. I always think about him and always remind about him. But some of his friends are kidding him by telling the name of another girl whom I know. i hate that. Im not used in talking to boys and no one of my friends know about these stuff and I dont like to tell them as well. but ofcourse i'm writing these stuff in my diary. so plz tell me, what should I do now and as i think i will be able to see him only till the end of the next year. what should i do???? am i in love with him or what?????. (there will be grammar mistakes in the description.sorry for that ) I'm 14 yrs old - A girl
And also I stare at him sometimes but he doesn't. I'M CRAZY OF HIM.
