Is it love? Or illusions? :( ♥

Okay, soo I like this guy at high school

He is a sophomore, and I'm a freshman, n when I see him I feel butterflies in my tummy, n I feel soo excited when I see him in the hall, he smiles too, when I go to lunch he always behind me, n he glares n looks at me a lot, he also rushes a lot when I'm close or near him, he gets nervous too

could this mean something? Am I making things up in my mind? Am I hallucinating,

I think I'm inlove, the first day that I saw him I fall for him,,, could this be love? Comment/suggest
