Why is my obsession this bad???

im a freshman in high school and there's this guy, my age. he is gorgeous funny and hot! some people would lablel him as emo. he is never at school, i know he is smoking pot, his junior brother stays home with him. i have 2 cl with him, so i'm only supposed to see him 2 times a day, but i kind of stalk him. my friend also think he's cute, so when we're done with lunch we go find him in the courtyard and make random excuses to go see him. also i go visit my friend in the bus loop to see him. i notice all the little things he does like when i catch him looking at me or how he looks gorgeous in his long sleeve shirt and a pair of faded jeans. we some times talk in pe but all we talk about is cl abd it is usually a 3 way conversation between me him and a girl we're both friends with. my obsession is so bad i had a dream about him last night. it was really weird we were in greece with my parents. thing is he really liked me in my dream. why is my obsession this bad?HELP!!!!
