Why do I still have these feelings that's preventing me to sleep , stomach aches , constantly thinking/ dreaming?

So there is this popular boy at my school , how this all started is because I would always have too walk pass him because I have to go too my class. Everyday he would stare at me , so I would look.. Though October started and it call came to me about what's going on , because the next day I catched feelings. Long story short this is altogether 7months of the school year this eye contact between me and him as been goin on , and yea a blushing and all that good stuff went on. So now we're in June , last week of school.. Nothing changed. Though it's the last day of school , my friends and I , and his friends and him was in the lunch line but his friends were behind me. I turned back everyone was crowded behind me and kept coming closer , my friend told me everything felt awkward , so I skipped her to prevent myself from being in the back. All that happened getting our lunch and etc. But he backed up and went to sit down , I sat and he came to sit next to my lunch table and was staring at me the whole time.. From my pher. Vision.. He would watch my every move. So school is almost over , I get up , he gets up.. I leave , then he leaves. I came back into the cafeteria he was gone. Now in the back of my mind as I came home , I cannot stop thinking about him , barely could sleep , stomach hurts , dreaming about him endlessly.. So does anyone know why?
