I am 15 (sopre) and I think I am in love.........Am i??

I like this kid ALOT.. you have no idea. I have never liked someone so much in my life, and I never wanted something so badly. So this kid lets call him.. (john?) So john is ridiculously goodlooking haha and i text him but he texs me (its mostly me being the first one to text him) but i am CONSTANTLY thinking about him.. Honestly, their is not one minute that I am not thinking about him. I am obsessed and I dont know why!!! When I think about him I get nervous and get this weird feeling and erflies in my stomach.. He's all I think about or talk about. My face lights up and I cant help to be anything but happy around him. When I look at him the same thing happens. Whats the next step? Am I in love? How do I get him?
